Because of Jesus unity with God, Jesus lived as God wanted him to live. Because of our identification with Jesus, we must honour him and live as he wants us to live.
Eternal life, living forever with God, begins the moment you accept Jesus Christ as our Saviour. New life begins in us, God completes the transaction. The rest of your life on earth will go better for you, even though you might face hardships, because your are living in fellowship with the Almighty Creator, who loves you. And though you will still face physical death one day, when Jesus returns again, your body will be resurrected to live forever.
