Have you learned to probe the sinner's conscience? This is something each of us must learn to do if we want to see sinners come to genuine repentance, whether in one-to-one witnessing or in preaching. The conscience is waiting to be resurrected. It lies dormant in the dark human heart, waiting for you to speak to it. It is like an echo. It will remain silent as long as you remain silent. So do what the Bible tells you to do: "Cry aloud, spare not, lift up thy voice like a trumpet, and show my people their transgression, and the house of Jacob their sins."(Isaiah 58:1) When you trumpet the Law of Moses, if you listen carefully, you might hear the echo as the conscience "bears witness."( See Romans 2:15) The conscience agrees with the Commandments. So, make sure you aim at the conscience when you speak to the lost. There goes another minute. Gone forever. Go share your faith while you still have time.
