Yes, in times of war there will indeed be casualties... but we carry on, not looking back understanding that sorrow can be an opening in our armor giving ol slewfoot a free shot at us!
God says mankind is without excuse so I don't sweat the petty things, and I certainly don't pet the sweaty things!
I heard recently that one of the Memphis Mafia guys that hung out with Elvis said he knew for a fact that Elvis was worried about his health and was doing a lot of ask for forgiveness and communicating with the Lord in prayer as best he knew how.
If the guy was sincere and acknowledged his sin before the Lord in repentance, I'd imagine we'll see him in Heaven... and no, they don't call him "king" there cause their ain't but One King!
