Christ-followers are never 100% "Completely Conformed " to the spiritual image of God the Son during the Sanctification Process!
Colossians 1:15
He (Jesus) is the image of the invisible God, the firstborn of all creation.
Hebrews 12 [ Jesus, the Example ]
Therefore, since we have so great a cloud of witnesses surrounding us (saved believers),
let us also lay aside every encumbrance and the sin which so easily entangles us, and let us run with endurance the race that is set before us,
fixing our eyes on Jesus, the author and perfecter of faith, who for the joy set before Him endured the cross, despising the shame, and has sat down at the right hand of the throne of God.
For consider Him who has endured such hostility by sinners against Himself, so that you will not grow weary and lose heart. ...
1 Peter 2:21 [ Christ Is Our Example ]
For you have been called for this purpose, since Christ also suffered for you, leaving you an example for you to follow in His steps,
??in our spirit being. we have been fully “conformed to the image of His Son” ??
Romans 8 (NASB)...Believers are Delivered from the Bondage of Sin at Salvation; their Sin Natures remain
1 Therefore there is now no condemnation for those who are in Christ Jesus.
2 For the law of the Spirit of life IN Christ Jesus has set you free from the law of sin and of death.
3 For what the Law could not do, weak as it was through the flesh, God DID:
sending His own Son in the LIKENESS of sinful flesh and as an (SELF) offering for sin, He condemned sin in the flesh,
4 so that the requirement of the Law might be fulfilled in us, who do not walk according to the flesh but according to the Spirit.
28 And we know that God causes all things to work together for good to those who love God,
to those who are called according to His purpose.
29 For those whom He foreknew, He also predestined to become conformed to the image of His Son, so that He would be the firstborn among many brethren;
30 and these whom He predestined, He also called;
and these whom He called, He also justified;
and these whom He justified, He also glorified.
Colossians 3: (NASB)
5 Therefore consider the members of your earthly body as dead to
immorality, impurity, passion, evil desire, and greed, which amounts to idolatry.
6 For it is because of these things that the wrath of God will come upon the sons of disobedience,
7 and in them you also once walked, when you were living in them.
8 But now you also, put them all aside: anger, wrath, malice, slander, and abusive speech from your mouth.
9 Do not lie to one another, since you laid aside the old self with its evil practices,
10 and have put on the new self who is being renewed to a true knowledge according to the image of the One who created him
— 11 a renewal in which there is no distinction between Greek and Jew, circumcised and uncircumcised, Cbarbarian, Scythian, slave and freeman, but Christ is all, and in all.
12 So, as those who have been chosen of God, holy and beloved, put on a heart of compassion, kindness, humility, gentleness and patience;
13 bearing with one another, and
forgiving each other,
whoever has a complaint against anyone;
just as the Lord forgave you, so also should you.
14 Beyond all these things put on love, which is the perfect bond of unity.
15 Let the peace of Christ rule in your hearts, to which indeed you were called in one body; and be thankful.
16 Let the word of Christ richly dwell within you,
with all wisdom teaching and admonishing [r]one another with psalms and hymns and spiritual songs, singing with thankfulness in your hearts to God.
17 Whatever you do in word or deed, do all in the name of the Lord Jesus, giving thanks through Him to God the Father.
2 Peter 1
4 For by these He has granted to us His precious and magnificent promises,
so that by them you may BECOME partakers of the divine nature, having escaped the corruption that is in the world by lust.
5 Now for this very reason also, applying all diligence,
in your faith supply moral excellence,
and in your moral excellence, knowledge,
6 and in your knowledge, self-control,
and in your self-control, perseverance,
and in your perseverance, godliness,
7 and in your godliness, brotherly kindness,
and in your brotherly kindness, love.
8 For if these qualities are yours and are increasing, they render you neither useless nor unfruitful in the true knowledge of our Lord Jesus Christ.
9 For he who lacks these qualities is blind or short-sighted, having forgotten his purification from his former sins.
10 Therefore, brethren, be all the more diligent to make certain about His calling and choosing you;
for as long as you PRACTICE these things, you will never stumble;
11 for in this way the entrance into the eternal kingdom of our Lord and Savior Jesus Christ will be abundantly supplied to you.
