The tree of Life represents the spiritual man,it represents justification by faith, it represents true righteousness through the Blood of Jesus (Romans 5:9). Romans 5:1 says,"Therefore, having been justified by faith we have peace with God through our Lord Jesus Christ." I am for all good works. As christians we understand good works are very important, but we also understand that we are not saved by works. We are saved by faith.(Ephesians 2:4-10, Titus 3:5, and Romans 3:21-31).Jesus is the Tree of Life.It is very important that you remember this scripture, 1John5: 11-12," that God has given us eternal life, and this life is in His Son. He who has the Son has life," and the way we receive this life is in Romans 10:8-10. "The word is near you, even in your mouth and in your heart.If you confess with your mouth the Lord Jesus, and believe in your heart that God has raised Him from the dead, you will be saved. For with heart one believes into righteousness, and with the mouth confession is made to salvation". If we believe this, first and foremost, then Godly works will proceed out of us because of the faith that is in us.
