Jesus became flesh and blood so that He could dwell among us, so that He, God, could become one spirit with us. God’s ultimate purpose was not merely for us to believe in Jesus, nor simply to take us to heaven someday, but to make us one spirit with Him now.
The Bible says that the one who is joined to the Lord becomes one spirit with Him. For this union to be possible, Jesus had to become flesh and blood. He also had to die to a selfish life and surrender everything to the Father. This is the nature of love.
The devil attempted to divert Jesus by appealing to self interest. Are You hungry? Then eat. Do You want luxury? Do You want fame? Jesus said no, because He desired oneness with us, and selfishness always destroys love and unity.
Jesus died to self in order to become one with us. In the same way, we die to self in order to mingle with Him. This is the glory of the cross, the death of the selfish life. Scripture says, “I am crucified with Christ.” This, and this alone, makes true union possible.
This is how we become one with our beloved Savior: by surrendering our self life in order to gain His life.
