Quoting OutlawMom *BC*:" thank you."
Sorry it took so long, I was out and had to fix dinner. Since you said he suffered for a while I think Revelation 21:4 would be good, "And he will wipe out every tear from their eyes, and death will be no more neither will mourning nor outcry nor pain be anymore. The former things have passed away."
Then about resurrection
John 11:25 "Jesus said to her, 'I am the resurrection and the life. He that exercises faith in me, even though he dies, will come to life."
Then one for encouraging his wife:
Psalms 18:2 "Jehovah is my crag and my stronghold and the Provider of escape for me. My God is my rock. I shall take refuge in him, My shield and my horn of salvation, my secure height."
I think too if she listens to the vocal renditions of the Kingdom Melodies she may feel better too. It's helped me a lot when I'm down.
If you need more ideas feel free to contact me, I'll do my best to help.
