Before salvation we are incomplete and strive to satisfy our hunger. But through the new birth, we are complete in Christ and our hunger should only be for more revelation of what we already have in Him. Total satisfaction with Jesus disarms satan's lies. A big part of all temptation is dissatisfaction.
Adam and Eve would not have eaten of the forbidden fruit if they hadn't been made dissatisfied with what they had. Satan's lie led them to believe that they didn't have it all (Genesis 3:5). The truth is, they did have it all. They were more like God before they ate of the fruit than after they ate the fruit. Their dissatisfaction was the beginning to their action of sin.
Satan tempts us in the same way he came against Adam and Eve, 2 Corinthians 11:3, "But I fear, lest by any means, as the serpent beguiled Eve through his subtilty, so your minds should be corrupted from the simplicity that is in Christ."
A full revelation of our completeness in Jesus will keep us from chasing after all the things the devil has to offer. If anyone tells you that He isn't enough; that you need something more, then that's the devil trying to turn you away from your completeness in Him.
In the same way that Jesus has the fullness of God in Him, we have the fullness of Him in us. That makes us complete or perfect in Him - that is our spiritual man.
Our born-again spirit is identical in righteousness, authority, and power to Jesus' spirit because our born-again spirit is the Spirit of Christ, "But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God dwell in you. Now if any man have not the Spirit of Christ, he is none of his."Romans 8:9. Galatians 4:6 "And because ye are sons, God hath sent forth the Spirit of his Son into your hearts, crying, Abba, Father."
