The entire war for the souls of mankind was won on the cross of Calvary. When we repent of sin, and give ourselves to Him, we are in Him, and are made the righteousness of God. The stone was not rolled away to let Jesus out, it was rolled away to let people see that Jesus was not there anymore! God worked at the trinity all throughout the old testament as well as the new. If you're in Him, you were resurrected with Him!! When Jesus rose, it made it possible for us to arise with Him. The final cry from the cross, was, "Father, into thy hands I commend my spirit." Then He gave up the ghost.
