@Taken I believe the Bible teaches Christians can fall under wrath for sinning. I tried linking you to the post, but I am not sure if you will follow a link, so I'll share it here.
1 Corinthians 9:26-1 Corinthians 10 show that salvation can be jeopardized by sin--that just as the Jews fell under God's wrath and forfeited His promise after having been saved, so, also, Christians can fall under God's wrath and forfeit His promise after being saved.
Some object, "This isn't about salvation, it is about rewards," but
i. Paul says that he may become disqualified, and we know Paul often refers to faith as a "race", so if he became disqualified from the race of faith, that would mean he wouldn't be in the faith (eg, 2 Co 13:5).
ii. Paul warns the Corinthians (1 Co 6), because of their shockingly unrighteous behavior, that the unrighteous will not inherit God's Kingdom, explicitly mentioning the immoral and idolaters, and, in 1 Co 10, Paul mentions both immorality and idolatry--and, by the reckoning of a person who denies this issue (righteous living after salvation) is an issue on which eternal life hinges, what they're saying is they would have no issue with a Christian a) living in sin, b) provoking God to jealousy and falling under God's wrath, and c) forfeiting God's promise.
Therefore, the issue is not "merely about rewards" (as if "rewards" could not encompass "eternal life"--this is just a misunderstanding, anyway, since "God will repay every man according to his deeds... to the one who persists in doing good... eternal life" (Ro 2:6-16), and "My reward is with Me to repay every man according to his deeds" (Rv 22:12)), but that it refers to eternal life.
1 Corinthians 9
25Everyone who competes in the games exercises self-control in all things. So they do it to obtain a perishable wreath, but we an imperishable.
So, what is the "wreath", which is a "crown", Paul looks to win by living righteously?
James 1
12Blessed is the man who remains steadfast under trial, for when he has stood the test he will receive the crown of life, which God has promised to those who love him
Revelation 2
10‘Do not fear what you are about to suffer. Behold, the devil is about to cast some of you into prison, so that you will be tested, and you will have tribulation for ten days. Be faithful until death, and I will give you the crown of life.
But what happens to people who do not love God in their deeds? Do they just get a "lesser prize"? Of course not! They're "accursed" (1 Co 16:22).
What happens to people who do not have a "crown of life"? Aren't they dead? Wasn't it sin that first resulted in Adam's death--and isn't 1 Co 10 addressing sin?
So, death is by sin, and Paul says he won't get the crown of life if he lives in sin.
Sin can jeopardize our "in Christ" status (1 Jn 3:23,24)--"life" is located "in Christ" (1 Jn 5:11). Sin is surmised by a command--falling short of it. The command is: i) believe in Christ, and ii) love one another (1 Jn 3:23,24). The "crown of life" Paul wants is by remaining in Christ, where "life" is. Not all believers remain in Christ (1 Jn 2:28; 1 Jn 5:21). There's "no condemnation" for those "in Christ" (Ro 8:1). There's condemnation on a Christian who doesn't walk in faith (Ro 14:23). If there's "no condemnation" for those in Christ, how is a believer condemned? The believer is not remaining in Christ--by not walking in faith, he is not loving others. We remain in Him, and are given Life, by obeying--i) believe in Jesus, ii) love one another. Loving others is another way of saying "walk by faith"--"faith works by love". When are walking in faith, we are walking by love--revealing God's righteousness (Ro 1:5, 16,17). Those who remain in Christ are supplied with the Spirit. The Spirit is the eternal life--the life that is only located "in His Son". There is no sin in Christ. Those who sin are not remaining, and won't get the life. This is the "crown of life" Paul wants. He wants the eternal life located "in Christ", supplied only those who "remain in Christ". It's clear.
