I am the father of a handicapped child. When he was born my wife and I thought our lives were over. We were very wrong. God's love will be made manifest in the world through this child.
God is already glorified in your testimony, K. Your son may be handicapped in a visible way....but all of us were (and some still are) handicapped by our often invisible sin. Praise be to Him who bore all of that in His own body for us. And we will stand with Him in that day.....
