"The serpent said to the woman, 'You will not surely die. For God knows that in the day you eat of it your eyes will be opened, and you will be like God, knowing good and evil.' So when the woman saw that the tree was good for food, that it was pleasant to the eyes, and a tree desirable to make one wise, she took of its fruit and ate" (Genesis 3:5-6). Discontentment is one of the deadliest aspects of human nature. We had been given the Garden of Eden. We walked with God. But we were deceived, and believed that there was more, that something had been kept from us. We were wrong.
The safeguard against the deception is to "have this attitude in yourselves which was also in Christ Jesus, who, although He existed in the form of God, did not regard equality with God a thing to be grasped, but emptied Himself, taking the form of a bond-servant, and being made in the likeness of men" (Philippians 2:5-6). You see, Jesus was also offered equality with God in Matthew 4:1-11, even though He is God, but He saw through the deception. And in the words of James 4:7, He submitted to God and resisted the devil, who then fled from Him.
The Lord calls to us in 1 John 2:15-17, saying: "Do not love the world nor the things in the world. If anyone loves the world, the love of the Father is not in him. For all that is in the world, the lust of the flesh and the lust of the eyes and the boastful pride of life, is not from the Father, but is from the world. The world is passing away, and also its lusts; but the one who does the will of God lives forever."
