Jesus makes it clear to Martha in John 11 that he more than has power to raise Lazarus — he is resurrection, he is life. Then he raises Lazarus from the dead. Jesus is wanting to pass on this part of his nature to all who believe in him. There is more taking place here than a great miracle done for the sake of Lazarus and his sisters, though that certainly is part of what is happening. There is a demonstration of his being the resurrection, of his being life and an encouragement for his followers to tap into this — eternally.
The more I study about how to overcome sin, the more I see we need the power of resurrection to do so. This is what enables us to be a new creation, to change our very nature. We have no hope of radical change without it.
How can you see the power of resurrection changing you?
