"God should punish that person who preached a false gospel forever" (see UDB). If your language has a common way of calling a curse down on someone, you should use that.

## For do I now want the approval of men or God? Or am I seeking to please men? ##

These rhetorical questions expect the answer "No." This could be translated as "I do not seek the approval of men but instead I seek the approval of God. I am not seeking to please men." (See: [[rc://en/ta/man/translate/figs-rquestion]])

## If I am still trying to please men, I am not a servant of Christ ##

Both the "if" phrase and the "then" phrase are contrary to fact. This could be translated as "I am not still trying to please men; I am a servant of Christ" or "If I were still trying to please men, then I would not be a servant of Christ."
