A man may preach from false motives. A man may write books, and make fine speeches, and seem diligent in good works, and yet be a Judas Iscariot. But a man seldom goes into his closet, and pours out his soul before God in secret, unless he is in earnest. The Lord Himself has set His stamp on prayer as the best proof of a true conversion. When He sent Ananias to Saul in Damascus, He gave him no other evidence of his change of heart than this,-"Behold, he prayeth" (Acts 9:11).
