One must choose his reward for actions taken. Would he rather receive eternal reward from God the Father, or temporary praise and recognition from his peers?
How would making your motive match the Lord's motive change how you approach the Christian life (from witnessing to praying to Bible reading and so on)?
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.
