Prayer for a Blessing on a Long Life of my Grandparents

Pray for my Grandparents to have a long life, and may the Lord bless them always. Pray that the Lord let them feel the tenderness and strength of His presence. Let them rejoice in His mercy as they look back to the past. And may the Lord protect and guide them always. Pray for my grandparents that God gives them the strength that they need. Thank you so much
