May I suggest Psalm 139 it really speaks to how the LORD has all this in His hand. I am a Grandpa too, and I sometimes think about what I am leaving for my grand kids. I pray Lord you will be with this family right now. Lord may your Holy Spirit Minister to these dear ones now and during the days that follow, in Jesus Name I pray Amen.
May God comfort you and your family as you mourn the loss of your grandpa. May He fill You all with His peace which passes all understanding, In Jesus Name, Amen
Father I pray blessings on this request and comfort for the family in Jesus name I pray. Also taking these needs before God in prayer on the 1:15PM bbnradio.org Family Altar program.
