I love my children and grandchildren and long to be with them eternally. The truth is—God doesn’t have grandchildren. I can pray for them, but they must choose. Like me, you will want to welcome your children into Heaven. The good news is, God has a plan for their life just as He has for yours and mine. 

“Arise, cry aloud in the night, At the beginning of the night watches; Pour out your heart like water Before the presence of the Lord; Lift up your hands to Him For the life of your little ones Who are faint from hunger At the head of every street.”
‭‭LAMENTATIONS‬ ‭2:19‬ ‭AMP‬‬

Pray and praise! Lift your hands for the life of your little ones!
