In 1 Corinthians 1:18 Paul says, "For the word of the cross is folly (foolishness) to those who are perishing, but to us who are being saved it is the power of God."

In other words, those who reject the gospel are fools (also note Rom 1:21-22). After all, what wisdom is there in rejecting God's love, mercy, and forgiveness in the atoning sacrifice of His Son for our sin and instead preparing to face his wrath alone?

We then see in Proverbs 26:4-5 the following council for responding to a fool's objections:

"Answer not a fool according to his folly,
lest you be like him yourself.
Answer a fool according to his folly,
lest he be wise in his own eyes."

At first glance, many mistakenly believe this proverb to be self contradicting. However, king Solomon in his wisdom was instructing that we are not to answer a fool on his terms. In other words, a fool has a false framework and to try to build upon that false framework is futile and foolish in and of itself. Instead, we are to answer a fool addressing where he has gone wrong, giving him a biblical framework so that he might not remain deceived, falsely thinking he is wise.

By example, when talking to an atheist, it is not profitable to try to give evidence for why God exists, nothing will satisfy their demands. Scripture is clear that the unrighteous suppress the naturally understood truth revealed in creation that God exists (Rom 1:18-19). One would be better off poking holes in the fact that the arguments against a Creator are weak and that the truth about God is obvious, then leading right into the gospel.

When talking to someone deceived by a false religion who objects to the biblical gospel, it is foolishness to try to answer their misguided challenges to the faith. Instead we ought to expose where their false framework is in opposition to a biblical framework and lead right into gospel truth.

May we not go down rabbit trails or run in circles regarding misguided objections and always come back to the gospel itself, exposing all that is opposed to it. I myself will testify that the errors in my former Catholicism were never clear until I began looking at them in light of a gospel centered biblical framework.
