A lost man cannot "put on the new man" because the "new man" is a work of creation (Eph. 4:24). He is addressing saved persons who are in the Romans 7:14-25 struggle. Lost people cannot put on or put off. The old nature, indwelling sin, they are to put off characterizes the lost condition and that is why they should put it off and put on the new man. Ephesians 4:17-20 has NOTHING to do with a saved man and Ephesians 4:21-32 has NOTHING to do with a lost man. You are jerking scriptures out of context and confusing them.
Verse 18 shows the lost man is "ignorant". We are alienated from God by ignorance, not some metaphysical inability.
Eph 4:18 Having the understanding darkened,
being alienated from the life of God through the ignorance that is in them, because of the blindness of their heart:
19 Who being past feeling have given themselves over unto lasciviousness, to work all uncleanness with greediness.
Unsaved people are ignorant, they do not know the true God and they do not understand righteousness. This is why Jesus commanded us to go into the world and TEACH the gospel to men.
Mat 28:19 Go ye therefore,
and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost:
20 Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world. Amen.
Jesus commanded us to teach men. This shows men have ability. Men LEARN of Jesus and this enables them to trust and believe in him. This is also how men's minds are renewed and they learn to live holy lives.
Eph 4:20 But ye have not so
learned Christ;
21 If so be that ye have heard him, and have been taught by him, as the truth is in Jesus:
22 That ye put off concerning the former conversation the old man, which is corrupt according to the deceitful lusts;
23 And be renewed in the spirit of your mind;
24 And that ye put on the new man, which after God is created in righteousness and true holiness.
25 Wherefore putting away lying, speak every man truth with his neighbour: for we are members one of another.
26 Be ye angry, and sin not: let not the sun go down upon your wrath:
27 Neither give place to the devil.
28 Let him that stole steal no more: but rather let him labour, working with his hands the thing which is good, that he may have to give to him that needeth.
29 Let no corrupt communication proceed out of your mouth, but that which is good to the use of edifying, that it may minister grace unto the hearers.
30 And grieve not the holy Spirit of God, whereby ye are sealed unto the day of redemption.
31 Let all bitterness, and wrath, and anger, and clamour, and evil speaking, be put away from you, with all malice:
32 And be ye kind one to another, tenderhearted, forgiving one another, even as God for Christ's sake hath forgiven you.
Men are saved by HEARING the word of God and LEARNING (John 6:45). This enables a man to believe in Jesus. Men also are renewed in their mind and become holy by learning and observing the word of God, by obeying God's commands such are given in this very passage of Ephesians where we are told to stop lying, to earn an honest living so we can support ourselves and help others, not to let corrupt words come out of our mouths, put away wrath and bitterness, to be kind, etc...
We are not ZAPPED to become holy, we LEARN to be holy by trusting God and obeying his commands.
