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.
Every unsaved person will have windows of opportunities when he becomes most receptive to the gospel of Christ. The Devil works hard to keep people in darkness and will distract them by every means necessary (i.e., the death of a loved one, a crying child, a ringing phone, busyness, etc.). The salvation of a soul involves a spiritual battle that can only be won by the Lord’s intervention. There is a window of time when the lost are most receptive to the gospel, likewise suggesting only a window of opportunity for the saved to speak for Christ. This is the very reason the apostle Paul stressed the importance of the saints of God beseeching the Lord to open to them a door of utterance (Ephesians 6:19).
