1 Corinthians 10:14

Wherefore let him that thinketh he standeth take heed lest he fall.

There hath no temptation taken you but such as is common to man: but God is faithful, who will not suffer you to be tempted above that ye are able; but will with the temptation also make a way to escape, that ye may be able to bear it.

I speak as to wise men; judge ye what I say.

The cup of blessing which we bless, is it not the communion of the blood of Christ? The bread which we break, is it not the communion of the body of Christ?
