This young convert was deeply impressed and determined to make these the rules of his life. From that day onward throughout his life he made it a rule to spend the first moments of his day alone with God and God's Word. Before he read a letter, looked at a paper or even read a telegram, he went first to the Bible, that the first impression of the day might be what he got directly from God.
