'Cause' in the Bible

For this reason I have sent Timothy to you, who is my beloved and faithful child in the Lord, and he will remind you of my way of life in Christ [my conduct and my precepts for godly living], just as I teach everywhere in every church.

Now food will not commend us to God nor bring us close to Him; we are no worse off if we do not eat, nor are we better if we do eat.

Only be careful that this liberty of yours [this power to choose] does not somehow become a stumbling block [that is, a temptation to sin] to the weak [in conscience].

Therefore, if [my eating a certain] food causes my brother to stumble (sin), I will not eat [such] meat ever again, so that I will not cause my brother to stumble.
