In the Garden of Eden man exalts himself to be a god in place of God. He succumbs to the temptation of the devil, and eating of the forbidden fruit he receives death. But in the sin-cursed wilderness God humbles Himself to become man in place of man. Jesus does not eat but fasts and bears the onslaughts of the devil for us that we may be restored to life. In the Garden man tries to win independence from God, to be his own master, to be in charge of his own life, and in the end man cuts himself off from all that is good. But in the wilderness, Jesus depends and relies on His heavenly Father, submitting to His will and looking to Him for all that He needs, in order that He might restore us to faith and to a right relationship with God. In the Garden, the tame and gentle animals that God had created fell under the curse of man's rebellion, turning against one another and against man himself. But in the wilderness, Jesus lived among the wild beasts (Mark 1:13), that He might experience the full effects of the fall and restore His creatures and renew all of creation.
It is for this reason that the Scriptures refer to Jesus as the second Adam. He came to undo and overcome the work of the first Adam. You and I are one with the first Adam. His blood flows through each of us. His rebellion dwells within us. We have participated in his sin. We are of the same nature. In Adam, we die. However, in Christ, we live. For we have also been made one with Christ through our baptism into His body. Jesus bore the sin of our old Adam and put it to death that we might be raised to a new life with Him. Now Christ's blood flows through each of us who have been made to be His members, particularly as we receive His blood and body in the Sacrament. God's love and faithfulness dwell within us by His Word and Spirit. St. Peter says that we have actually been made to be partakers of the divine nature through the flesh of Christ (2 Peter 1:4).
