Jesus was our obedience substitute during his life, our punishment substitute in his death, and our rebirth substitute in his resurrection. When we become united with Jesus, his life of obedience, his painful death, and his resurrection into glorious power are all credited to us. When someone becomes a Christian, a spiritually dead person is united with a life-giving one. His resurrection produces a resurrection in us. We are connected to the same power that raised Christ from the dead.
