No man is ever the same after God has laid His hand upon him. He will have certain marks, and though they are not easy to detect perhaps we may cautiously name a few.
One mark is a deep reverence for divine things. A sense of the sacred must be present or there can be no receptivity to God and truth. This mysterious feeling of awe precedes repentance and faith and is nothing else but a gift from heaven.
Another mark is a great moral sensitivity. Most persons are apathetic, insensitive to matters of the heart and the conscience, and so are not salvable, at least not in their present condition.
But when God begins to work in a man to bring him to salvation He makes him acutely sensitive to evil. Inward repulsion toward the swine pen that rouses the prodigal and starts him back home is a gift of God to His chosen.
