"Every day is a gift. Yes, they are a gift from God, but for the discerning Christian they are also a gift to God. The Lord grants us breath, health, and strength. We, in turn, give each day back to Him as a gift of gratitude. The Lord gives life and we are to live each day for His glory." (Read more about this article, click on the link above.)

"D. L. Moody made a covenant with God that he would witness for Christ to at least one person each day. One night, about ten o'clock, he realized that he had not yet witnessed; so he went out in to the street and spoke to a man standing by a lampost� The man flew into a violent and threatened to knock Moody into the gutter."

"Dwight L. Moody didn't attend school beyond the fifth grade; he couldn't spell, and his grammar was awful. His manners were often brash and crude, and he never became an ordained minister. Once, before his conversion, he so outraged an Italian shoe salesmen with a prank, that the man chased him with a sharp knife, clearly intending to kill him. Yet, Dwight L. Moody was used by God to lead thousands of people to Christ." (Read more about this article, click on the link above.)
