When Adam took the forbidden fruit, he denied God's sovereignty, and sinned against Him. When God wanted Adam to accept responsibility for his actions, Adam refused, and lost the manhood God had given him. Adam was distracted to the point that he tried to hide from the God who made him and ultimately was dislocated from the garden God had provided. The final destruction came in the form of spiritual death, for Adam and all his offspring forever. Another example is an adulterer who is deceived into thinking no one will know, denies doing anything wrong, is distracted in mind by the illicit, is dislocated physically by going where he should not, and eventually destroys the marital relationship.
Denial is a barrier that prohibits cures, healing, help, and salvation of every kind.
Say NO to sin. Sin promises to serve and to please but in reality enslaves and dominates your mind and body. Learn from observation. Not all lessons have to be learned by experience. Learn from your family, history, and the Bible.
