Certainly we also shall be in the likeness of His resurrection

Romans 6:5
For if we have been united together in the likeness of His death, certainly we also shall be in the likeness of His resurrection,

When we accept Yshua as our Lord and Saviour, we identify with His Crucifixion, and then we also identify with His Resurrection. We should be dead to our sins and become alive in Him. The Holy Spirit who comes to live in us, is part of this Resurrection life. This process is also well symbolized by the ritual of baptism.

After this Resurrection, we still have our own will. However we are to give ourselves in to the control of the Holy Spirit. Though we have been made alive with Christ, we are still living and trying to conform with His perfect image.
