Kelly revealed that the baby's "procedure" is scheduled for 7 a.m. on Wednesday and asked fans to keep the baby in their prayers."We are standing on the unshakable truth that God is the One who created our strong and courageous grandson…the One who formed him, knows him, and loves him even more than we do," Kelly wrote."We are holding on to every promise He has spoken in His Word — because even in this heart-wrenching pain, we believe HE is faithful. This road has brought us to our knees..There have been moments when tears wouldn’t stop. Moments when all we could do was cry out in anger, anguish, and pain."
