'Weak' in the Bible

Instead, God has chosen what is foolish in the world to shame the wise, and God has chosen what is weak in the world to shame the strong.

We are fools for Christ, but you are wise in Christ! We are weak, but you are strong! You are distinguished, but we are dishonored!

However, not everyone has this knowledge. In fact, some have been so used to idolatry up until now that when they eat food offered to an idol, their conscience, being weak, is defiled.

But be careful that this right of yours in no way becomes a stumbling block to the weak.

For if someone sees you, the one who has this knowledge, dining in an idol’s temple, won’t his weak conscience be encouraged to eat food offered to idols?

Then the weak person, the brother for whom Christ died, is ruined by your knowledge.

Now when you sin like this against the brothers and wound their weak conscience, you are sinning against Christ.

To the weak I became weak, in order to win the weak. I have become all things to all people, so that I may by every possible means save some.
