'Incentive' in the Bible

We are not commending ourselves to you again, but are giving you an occasion to be [rightfully] proud of us, so that you will have an answer for those who take pride in [outward] appearances [the virtues they pretend to have] rather than what is [actually] in heart.

But what I am doing I will keep doing, [for I am determined to keep this independence] in order to cut off the claim of those who want an opportunity to be regarded just as we are in the things they brag about.
