A dictionary defines “sanctification” as “the state of holiness and purity.” In our lives in Christ, “sanctification” is a state in which man, who had been corrupt because of his sins, is without any sins after receiving the grace of salvation through Jesus Christ and having been transformed by faith and by the power of the Holy Spirit. In such a state where only goodness and no evil are found, there is “righteousness” (what God deems “righteous”); this refers to keeping God’s commandments, which are God’s will itself. More specifically, through sanctification the corrupted mankind enters the state without any sin by the grace of the redemption of Jesus Christ. In other words, it is salient strength by which an individual becomes cleansed and made pure from the original sin and self-committed sins and from all filth both in flesh and spirit. Therefore, sanctification is the restoration of God’s image in which mankind was formed and became living beings (Genesis 1:27; 2:7) and partaking of the divine nature (2 Peter 1:4).

01. BIBLICAL SANCTIFICATION
For the prudent research of the Bible serves to best demonstrate the doctrines and experience of sanctification, it will be cited in this segment to address a number of important topics.

 ① SANCTIFICATION A NEW TESTAMENT STANDARD THAT IS OUGHT TO BE MET AND EXPERIENCED BY ALL BELIEVERS. 

 01  IT IS THE OF GOD FOR HIS PEOPLE TO BE HOLY(EPHESIANS 5:17~18)
In order to be wholly filled with the Holy Spirit, it is indispensable for God’s children to become sanctified (1 Thessalonians 4:3).

 02  GOD PROMISED HIS PEOPLE TO SANCTIFY THEM(ISAIAH 1:18)
John the Baptist said, “As for me, I baptize you with water for repentance, but He who is coming after me is mightier than I, and I am not fit to remove His sandals; He will baptize you with the Holy Spirit and fire” (Matthew 3:12). Clearly evident in this Verse is the inner and spiritual sanctification brought forth by the baptism by the Holy Spirit; John’s baptism was for the forgiveness of sins and the baptism by the Holy Spirit is to rid oneself of the core of sin.

 03  GOD ‌COMMANDS HIS PEOPLE TO BECOME SANCTIFIED(1 PETER 1:16)
‌God demands that His people be holy and commanded so as a precept and by example. God’s sanctification is also proactive and realistic, never restricted by consciousness (Genesis 17:1; Matthew 5:48). This indicates the perfection of love, the kind of love that is gained after one’s spirit has fought off all that is adverse to him (Mark 12:30; Romans 5:5).

 ② ‌PERFECT SANCTIFICATION IS A TWO-STEP WORK OF GODS GRACE(ROMANS 12:1~2) 

‌This refers to the necessity for a believer to remove his propensity toward the world and its ways as well as conforming to the world from his inclination to sin as his heart is renewed. It also clearly reminds all believers to correctly distinguish and experience all that is good, all that is acceptable to God, and His perfect will (2 Corinthians 7:1)

01. WAYS TO ACCOMPLISH RIGHTEOUSNESS
When we give birth to spirit by the Holy Spirit after accepting Jesus Christ (Acts 2:38), our names are recorded in the book of life in the heavenly kingdom and we become God’s children. From that point on, God declares that we are “justified” or “righteous” by our faith (Romans 3:24). However, we will have been “declared righteous,” not yet “made righteous.” Therefore, when we shun and cast out sins by diligently hearing His Word and distinguishing sin from righteousness (John 16:8), God will also deem our works “righteous.”
However, shunning and casting out sins is a duty for all children of God; it does not warrant them to be commended. In other words, even if we have cleaned a golden vessel on the outside, our work is not yet complete. We must remove all the impurities that have contaminated the golden vessel and other materials that have been mixed and become parts of the vessel from the failure to thoroughly refine the gold.
Toward This End

 ① WE MUST MARCH ONWARD IN THE KIND OF FAITH BY WHICH WE CAN CREATE SOMETHING OUT OF NOTHING AFTER DESTROYING ALL FLESHLY THOUGHTS AND SPECULATIONS. 

▶Instead of relying on our experience or knowledge, we must believe in God’s Word exactly as we find it.
▶We must not be focused on the realities but set our sight on the outcome with eyes of faith.
▶We must demonstrate truth, the outcome of our faith.

 ② We must destroy our own will and become obedient to God’s Word. 

▶True obedience is found in being obedient to that which we cannot be obedient.
▶We must be obedient with the assurance of faith.
▶In obedience, we must be able to say from our heart, “If I perish, I perish.”

 ③ We must please (move) God by works. 

▶We must fill our heart with goodness.
▶Our works must be with a devoted heart to seek other people’s interests first.
▶We must never hesitate to do God’s will.

02. A WHOLLY SPIRITUAL PERSON

① A Wholly Spiritual Person Is... 

When, through Jesus Christ, an individual receives forgiveness of his sins and gives birth to spirit by the Holy Spirit after receiving the authority to which he is entitled as a child of God, he will come to learn that there is an eternal world and lead a diligent life in Christ in an earnest hope for heaven. For he will have come to know that flesh is useless and spirit is worthy and everlasting, the individual will not only strive to shun and cast out his sins, do righteous works, become a spiritual person, but will also earnestly desire to have his spirit and soul and body be preserved complete, without blame at the coming of our Lord Jesus Christ (1 Thessalonians 5:23)

▶A wholly spiritual person possesses the kind of faith that will not waver or change in any circumstances.
▶A wholly spiritual person possesses a sanctified heart.
▶A wholly spiritual person receives all things for which he asks God in prayer.

 ② Becoming a Wholly Spiritual Person 

We had once been of the flesh but after receiving the forgiveness of our sins through Jesus Christ, we now dwell amidst the blessings as God’s children. With His Word and the Holy Spirit by our side, we have come to know about the eternal world, that flesh is useless, and that only spirit is truly valuable. By keep reminding ourselves the ways by which we can become wholly spiritual, we must continue to transform ourselves by whole spirit.

▶We must learn “spirit,” which is the truth, engrave it in our heart and desire it.
We must discover all that is flesh within us and completely destroy it.
  ▷We must cut off the lust of the eyes and thoroughly cast out the lust of the flesh.
  ▷We must destroy all fleshly speculations and thoughts.
▶We must pursue the desires of the Holy Spirit and live by His voice and guidance.
▶As we must pray without ceasing, we must pray fervently.

 01  THE REDEEMER MUST BE A MAN.

03. EVIDENCE OF SANCTIFICATION

 ① As sanctification is a transformation taking place in an individual’s heart, the person’s life is consecrated. 

 ② Sanctification is an inner transformation by which one gains freedom and triumph. 

 ③ The significance of sanctification exceeds the atonement of self-committed sins and cleanses the heart from the original sin and/or inherited depravation. 

 ④ Sanctification not only removes the liability for the sins but also brings the peace in a person’s heart as it destroys the forces of sin. 

 ⑤ Sanctification takes believers’ Father-children relationship with God a step further; by sanctification they can recover the lost image of God. 

 ⑥ Sanctification enables believers to become proactively devoted to God and lead their lives as His witnesses. 

 ⑦ Sanctification bears the fruit of spiritual love ? the perfect kind of love. 

 ⑧ Sanctification bears the fruit of the Beatitudes. 

 ⑨ Sanctification bears the fruit of the Holy Spirit and enables believers to cast out their old selves and works. 

04. NECESSITY FOR SANCTIFICATION

 ① Sanctification is the will and commandment of God for the corrupt mankind (1 Thessalonians 4:3-7; 1 Peter 1:15-16; 1 Thessalonians 5:23; Matthew 5:48).

 ② Sanctification is the goal of the gospel (Romans 8:29-30; 1 Corinthians 1:30; Malachi 2:15). 

God cultivates mankind on the earth in order to gain true children, devout and godly. Here, “true children” refer to God’s children who will have completely recovered the image of God their Father.

05. SECRETS TO MAINTAINING THE GRACE OF SANCTIFICATION

 ① Let His Word “Abide” in You (1 John 2:24) 

This experience refers not to living off something else (i.e. as a parasite) but to living within an object or another living being ? it is a life of its own, a scope of activity, and spiritual contact. “Abiding” does not require renewed devotion on a regular basis but is constantly walking with God in every moment of one’s life in His newly given light.

 ② Obey‌ (1 Samuel 15:22) 

True obedience is not a reckless rush after having a blind impulse but an intelligent “Amen” attitude within God’s will. Upon realizing that a certain task is of God’s will, immediate obedience must follow. Obeying that which can be obeyed is a given; obeying that which cannot obeyed must also be methodically done unconditionally. God’s Word can be divided into four large categories. The first are “Do” commandments including “Pray,” “Rejoice,” Be thankful,” and the like. The second are “Do not” commandments, including “Do not be envious or jealous,” “Do not harbor evil thoughts,” and the like. The third are “Throw away” commandments including, “Avoid every kind of evil,” and the like. The last are “Keep” commandments including “Keep the Sabbath holy,” “Keep thy heart with all diligence” (Proverbs 4:23, KJV), and the like. These four categories of commandments must be obeyed continually.

 ③‌Be on the Alert (1 Peter 5:8-9) 

Each believer must have a strict set of self-consciousness by asking himself the following questions:

▶‌Have I drawn nearer to God in prayer today, or have I become lazy and indulged in useless cravings?
▶‌Have I let down guard of my faith and has it thus become weaker? Or Am I making every effort to keep it alive?
‌▶‌Am I doing everything by faith? Am I acknowledging God in all my ways? Am I telling His will apart from everything else that isn’t?
▶‌Remembering that “When there are many words, transgression is unavoidable” (Proverbs 10:19), have I refrained my tongue today?
▶‌In how many ways and dealings have I taken up the cross and denied myself today?
In addition, a believer must also be on the alert and spiritually awake with God’s Word by his side.

 ④ Pray (1 Thessalonians 5:17) 

 ⑤ Maintain Close Communication with the Holy Spirit to Always be Filled with the Holy Spirit (Ephesians 5:18)
