But for the condition which Paul stated more than once "eternal life in Christ Jesus our Lord." Being "in Christ" is not automatic each person must make a willing, conscious decision.
When Paul wrote Rom 6:23 did he forget what he wrote in these verses. Twenty seven [27] groups of who have no inheritance in the kingdom of God.
1 Corinthians 6:9-10
(9) Or do you not know that wrongdoers will not inherit the kingdom of God? Do not be deceived: Neither the sexually immoral nor idolaters nor adulterers nor men who have sex with men
(10) nor thieves nor the greedy or drunkards nor slanderers nor swindlers will inherit the kingdom of God.
Galatians 5:19-21
(19) The acts of the flesh are obvious: sexual immorality, impurity and debauchery;
(20) idolatry and witchcraft; hatred, discord, jealousy, fits of rage, selfish ambition, dissensions, factions
(21) and envy; drunkenness, orgies, and the like. I warn you, as I did before, that those who live like this will not inherit the kingdom of God.
Ephesians 5:5
(5) For of this you can be sure: No immoral, impure or greedy person—such a person is an idolater—has any inheritance in the kingdom of Christ and of God.
1 Corinthians 3:17
(17) If anyone destroys God's temple, God will destroy that person; for God's temple is sacred, and you together are that temple.
