It is not just about the cross but also about the tomb. Easter morning the tomb was empty. He was not there. "Because He lives, you shall live also." Do we? Or, do we call our lives hard names, and stay in the safety of the despair of our tombs and try to call it life?
Oh, the wildflowers of Easter I see on my bike rides, the peaceful feeling of a run well done, the rhythmic power of some good swim strokes in the soothing medium of water, the little children with their Easter baskets, the vibrant green grass, the singing birds, and the eternal Hope in my heart, which says "come on out, you are free from the law of sin and death, come on out to embrace the life I have called you to. I have paid the price; I have rolled your stone away from the tomb."
He is alive, and because He lives, I shall live also.
