They all joined together constantly in prayer, along with the women and Mary the mother of Jesus, and with his brothers. Acts 1:14
Do you have children, grandchildren, or children whom you love — related to you or not — who have turned away from God? Years may pass without any apparent external change. But heaven hears your loving intercession on their behalf. Take heart! God hears your prayers for your children.
If you don’t have any of the above, it’s fine. Spend some time praying for those who have walked away from the faith of their mother or father. Ask God to hear your prayers and bring the straying children home.
