I am a christian, i gave my life to the Lord when i was young, yet since then i have messed things up. I have been married 3 times, i Have come to the Lord and asked for forgiveness, But does this mean i have to leave the woman i am with, to be right with the Lord? I look at 1 cor 7 and see Paul writing about adultery, I feel broken and Guilty by what i have done, and to feel i could of messed up on my salvation thanks for any help in this matter. Ben

As God is the one who sent his son to become the author of our salvation, do you really think you could mess it up? I won't try to tell you that your past choices may not bring about undesirable repercussions that you may have to deal with for a long time, but those things cannot change the miraculous reality brought about in Christ by which he made you a new creation in Him. All the begging and the guilt and the shame and the feelings that you're broken will only keep you locked within the perception of the fleshly religious lie. If your heart has truly been telling you anything in all of this, I'd have to say that it has been testifying of the real and living connection that remains between you and the one you have been joined to through Christ. If you want to really discover what Paul may have been desiring for those believers in Corinth, you might want to follow the letter to its conclusions in the second letter where he described his joy in knowing that their hearts were true even in the midst of all the stuff he wrote about in the first letter. In the end, he wanted them to understand how the religious abusers among them had been intimidating them to examine everything according to appearance rather than according to Christ and him crucified.

For the love of Christ controls us, having concluded this, that one died for all, therefore all died; and He died for all, so that they who live might no longer live for themselves, but for Him who died and rose again on their behalf. Therefore from now on we recognize no one according to the flesh; even though we have known Christ according to the flesh, yet now we know Him in this way no longer. Therefore if anyone is in Christ, he is a new creature; the old things passed away; behold, new things have come. Now all these things are from God, who reconciled us to Himself through Christ and gave us the ministry of reconciliation, namely, that God was in Christ reconciling the world to Himself, not counting their trespasses against them, and He has committed to us the word of reconciliation. 2 Corinthians 5:14-19

If the voice of condemnation you've been listening to cannot recognize the overwhelming reality of the new creation as described by Paul then it has no business trying to tell you what the rest of the letter might mean. Are you forgiven? Listen to this: God was in Christ reconciling the world to Himself, not counting their trespasses against them. God counts nothing against you! His viewpoint is not based upon him turning a blind eye, but rather that his is the only true viewpoint because of the reality brought about in Christ. The good news is so much better than anything perceived by the mind of religious man. Rejoice in this, my friend!
