The resurrection turns the ultimate defeat into the ultimate victory. Sin, death and Satan have now been dealt with forever because the Son of God has risen from the grave. The consequences of humanity’s fall into sin are reversed, never to take control of us again.
Just before issuing his Great Commission to the disciples, Jesus said, “All authority in heaven and on earth has been given to me.” That means the sin, death and Satan combined have approximately zero authority.
Since this deals once and for all with our biggest problem, lesser problems also come into a proper perspective. All of the hurts, problems and defeats that I have experienced or that I have caused are reduced to times that my team and I have fallen behind in a winning game. It may look bad for the moment but our final victory is ultimately assured.
There is never a reason big enough to give up hope. Christ is risen and someday we too will be resurrected into a completely new life in him.
