God created man without sin. In his infancy, man had no knowledge of evil but knew only the joys of fellowship with God. The first man had a perfect environment, a perfect spouse, and an uncorrupted mind. He had little in the way of commandments as God only gave one “thou shalt not” (Genesis 2:16-17). Of all the things man could have done within the will of God, man chose to violate God’s one restriction by partaking of the tree of the knowledge of good and evil. Immediately man’s eyes were opened to good and evil, and he died spiritually just as God had promised. In order to rescue man, God sacrificed an animal, providing coats of skin to cover man’s nakedness, and removed him from the garden.
Many Bible passages connect watchfulness and prayer. While preaching sounds the trumpet of alarm in the ears of men, prayer sounds the alarm in the ears of God. As a watchman, each believer has a responsibility to his brother or sister in Christ. While some believers are spiritually sleeping, unaware of their present danger, other believers ought to be standing upon the tower of watchfulness and calling upon the Lord. This was the point of Paul’s teaching in Ephesians 6:18 when he said, “Praying always with all prayer and supplication in the Spirit, and watching thereunto with all perseverance and supplication for all saints.”
