The young Christian came back laughing. He had the answer to the big question. Because you are spiritually dead, just like those ducks. He goes after the live ones, ones like me. Those who are Satan's workmanship are dead in their transgressions and sins.
Life is a walk, a journey, a pilgrimage, a taking of step after step in a certain direction.
God wants us to follow, to walk, the path of righteousness. Those, however, who are Satan's workmanship walk the path of sin and evil and darkness. Theirs is not the path that leads to life. Man's desires and thoughts are dominated by self-centered passions. He wants to do the things of the flesh that God forbids in His Ten Commandments.
