For since, according to God's [true] wisdom, the world did not know about Him through its wisdom, God was pleased to save those who believe [in Christ] through the "foolishness" of the message preached.

I behaved like a weak person in front of weak people [See 8:9-12], in order to win them over [i.e., to help them become stronger]. I have become all things to all people so that, in every way, I could save some of them.
