God working in lives:

King James Version (Chapter 11)

And when ye stand praying, forgive, if ye have ought against any: that your Father also which is in heaven may forgive you your trespasses.

King James Version (Chapter 12)

And lest, when I come again, my God will humble me among you, and that I shall bewail many which have sinned already, and have not repented of the uncleanness and fornication and lasciviousness which they have committed.

Paul says this most interesting thing, my God will humble me, but he prefaces this with: lest, that is to say, in fear of God humbling me. Now what can this humbling truly mean other than, if Paul does not admonish the Corinthians, for not repenting of their sins, that he himself will no longer be in right standing with the Lord Christ Jesus; for, although we are not to judge, we are to admonish the obvious works of the flesh....

Now Christ Jesus says this same thing, but not exactly in the same way; still, the consequences of what Christ Jesus is saying are far more severe to the individual. Christ Jesus says that unless we forgive our brethren, we will not be forgiven; meaning God cannot go against himself, and he can only forgive if we first forgive. Clearly, see, this statement of Christ Jesus, he is not telling us to forgive those people who are sinning against God -- as is the case with St. Paul admonishing the Corinthians for their sins, but Christ Jesus is saying if, we have ought against any that we must forgive, so that God can forgive us. However, St. Paul fears that he will have to bewail that is admonish the Corinthians for some have reprobate minds and he has said that he would not spare them when he comes again, but will reprove them, openly for their sins.

So in these two verses we have God telling us, unless, we forgive the person who sins against us that God will not forgive us and then we have St. Paul telling us that he fears the Lord will humble him, and then, in order for St. Paul to continue to be in right standing with God the Heavenly Father, that is, being in God’s righteousness, that he will have to bewail them for their sins and sinfulness or in other words, St. Paul will have to admonish them for their sinful behavior.

Then Paul tells them that they are to examine themselves to see if they are reprobates, and here, we go to Romans 1:28 and truly we should examine Romans 1:24-32 to see what it means to have a reprobate mind and if indeed we may have one,,,,
