There is always a temptation to track numbers when it comes to evangelism. It is wise not to do so, because only God knows those who are truly repentant. It is amazing how many evangelists and preachers seem to have access to the Book of Life by citing salvation statistics, but such numbering reveals a lack of understanding of the nature of true and false conversion. Making a “decision,” walking an aisle, or raising a hand do not indicate whether someone truly repents and trusts in the Savior. The fact that we have planted the good seed of the Word of God is evangelistic “success.” The rest is up to God.
Regarding keeping tabs of “decisions for Christ,” D. L. Moody stated: “‘Is it well to number converts?’ [David] got into trouble by trying to number Israel. It is best to let the Lord keep the record. It makes me creep all over to hear a man tell how many he has converted.”
1 Chronicles 21:1 Now Satan stood up against Israel, and moved David to number Israel.
