You'll just have to trust me when I tell you that I have only experienced that emotion once before ... when he stood in the same place with our daughter.
I have no greater joy than to hear that my children walk in truth. 1 John 1:4
I know that I am taking this verse out of context, but it comes closer to capturing how thankful I am for the blessing of my children's salvation than any thing else I could think of. I hope you'll understand.
