It is not the being seen of men that is wrong, but doing these things for the purpose of being seen of men. The problem with the hypocrite is his motivation.
If we cooperate with Him in loving obedience, God will manifest Himself to us, and that manifestation will be the difference between a nominal Christian life and a life radiant with the light of His face.
It does not require great art, or magnificently trained eloquence, to prove that Christians should tolerate each other. I, however, am going further: I say that we should regard all men as our brothers. What? The Turk my brother? The Chinaman my brother? The Jew? The Siam? Yes, without doubt; are we not all children of the same father and creatures of the same God?
The greatest proof of Christianity for others is not how far a man can logically analyze his reasons for believing, but how far in practice he will stake his life on his belief.
The Lord says, 'Whoever has, to him shall be given' (Mt. 13:12). He will give, then, to those who have; that is to say, if they use freely and cheerfully what they have received, He will add to and perfect His gifts.
