Martyn Lloyd-Jones
We must stand firm in the truth, in the message, for without it we have no power. We may be very nice and kind to one another, but that will not convince the world of sin, and bring them to Jesus. The truth alone can do that.

For whoever finds me finds life and obtains favor from the Lord, but he who fails to find me injures himself; all who hate me love death.
Proverbs 8:35-36
