1 Corinthians 15:22 (NRSV): “for as all die in Adam, so all will be made alive in Christ.”
Romans 5:15 (NRSV): “But the free gift is not like the trespass. For if the many died through the one man’s trespass, much more surely have the grace of God and the free gift in the grace of the one man, Jesus Christ, abounded for the many”
many being a semitism for all.
All mankind are "in Adam" for all mankind are literal descendants of Adam but all mankind are not inherently "in Christ" that requires a personal, voluntary act on the part of each individual.
Romans 3:24 Being justified freely by his grace through the redemption that is in Christ Jesus:
Not in Christ, no redemption.
Romans 8:1 There is therefore now no condemnation to them which are in Christ Jesus, who walk not after the flesh, but after the Spirit.
Not in Christ and walk after the flesh, still condemnation
2 Corinthians 3:14 But their minds were blinded: for until this day remaineth the same vail untaken away in the reading of the old testament; which vail is done away in Christ.
Not in Christ, the veil is not taken away, they remain blind.
2 Corinthians 5:17 Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new.
Not in Christ, not a new creature, old things are not passed away.
Ephesians 1:10 That in the dispensation of the fulness of times he might gather together in one all things in Christ, both which are in heaven, and which are on earth; even in him:
Not in Christ, not gathered together.
Ephesians 2:13 But now in Christ Jesus ye who sometimes were far off are made nigh by the blood of Christ.
Not “now in Christ,” still afar off, not nigh.
2 Timothy 2:10 Therefore I endure all things for the elect's sakes, that they may also obtain the salvation which is in Christ Jesus with eternal glory.
Not in Christ, do not obtain salvation or eternal glory.
Galatians 2:16
16 Knowing that a man is not justified by the works of the law, but by the faith of Jesus Christ, even we have believed in Jesus Christ that we might be justified by the faith of Christ, and not by the works of the law: for by the works of the law shall no flesh be justified.
Not “in Jesus Christ” not justified by faith
1 Thessalonians 4:14
14 For if we believe that Jesus died and rose again, even so them also which sleep in Jesus will God bring with him.
Those who are not in Jesus, God does not bring with Him.
When Paul wrote 1 Corinthians 15:22, above, do you think he forgot what he wrote in 1 Cor 6:9-10 and the other verses below and vice versa?
1 Corinthians 6:9-10
Know ye not that the unrighteous shall not inherit the kingdom of God? Be not deceived: [no wrongdoer] neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor abusers of themselves with mankind,
10 Nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners, shall inherit the kingdom of God.
Galatians 5:19-21
19 Now the works of the flesh are manifest, which are these; Adultery, fornication, uncleanness, lasciviousness,
20 Idolatry, witchcraft, hatred, variance, emulations, wrath, strife, seditions, heresies,
21 Envyings, murders, drunkenness, revellings, and such like: of the which I tell you before, as I have also told you in time past, that they which do such things shall NOT inherit the kingdom of God.
Ephesian 5:5 For this ye know, that no wrongdoer no whoremonger, nor unclean person, nor covetous man, who is an idolater, hath any inheritance in the kingdom of Christ and of God.
1 Corinthians 3:17 If any man defile the temple of God, him shall God destroy; for the temple of God is holy, which temple ye are.
