Trusting in HIM, sometimes means we have to leave our troubles at the foot of the cross and accept that HE is in Charge!!! YES?
Hardest thing for me personally is to give thanks for what is already asked, believing it is already answered... THAT is faith, they say...but sometimes beyond my mortal abilities.
I'm sure God has your grandchild in his loving arms, but now I will pray for you and your wife to know the peace that passes all understanding.
Keep the Son in your eyes!
