The new Adam is Jesus Christ whose bloodline is spiritual. Just as Adam the man had a bloodline that led to Abraham who was blessed to be called the father of Israel, so Jesus Christ calls his father God and his bloodline the church (1 Corinthians 15:22 & 23).
Christians talk about putting the old man to death so that new man can live forever (Ephesians 4:22). The new man is the spiritual life that is born in a person when that person believes in Christ as the Son of God . This is what “born again” means (John 3:10-17). The old man is the evil one who hungers to over indulge in sensual pleasure, the one that was born from his mother’s womb (Romans 6).
When the new spiritual man is born again within us, we undergo a transformation in which we begin to hunger for obedience to God (Romans 12:2). Understanding what God requires from us comes from within our conscious minds because our thoughts are turned to Him (Romans 2: 14 & 15; 10:8). This spiritual rebirth within us grows stronger as we feed it with the knowledge of God provided in the Bible (1 Corinthians 2:12-14), with loving kindness towards others (Matthew 5:16), and with prayer (Acts 2:42-47). It is this spiritual man who will rise again and live forever in a new, incorruptible body (1 Corinthians 15:52 & 2 Corinthians 5:1-5).
The New Testament is a mirror image of the Old Testament, only it is spiritual in nature while the Old Testament is physical. Jesus Christ is the sacrificial lamb that the Old Testament required for forgiveness of sins (1 Peter 1:18-20). That is why Christians “eat his body and drink his blood” symbolically with bread and wine (Luke 22:18-20). The New Testament describes 38 events in the life of Christ that fulfill the Messianic prophecies in the Old Testament. Even the important events of Christ’s death coincide with important feast days celebrated in the Old Testament.
Jesus Christ’s life and words, his loving acts of kindness even to death on the cross, and his promises for a future in heaven with him are so beautiful that Christians are unable to retain even a portion of understanding without meditation, prayer, and constant reading to remind us of the depth of his love (1 Corinthians 13:12). Though many people hear that the second coming of Christ will involve great suffering, the truth is that it will also provide a new world of such beauty and love that the entire earth groans in expectation of it. Christians cannot put into words the longing that is within us to see this new world with our Savior but the Spirit within us knows and it groans deeply for the Lord God to come (Romans 8:22-26).
