Jesus help this man come to know you as his Lord and Savior and know all his sins are forgiven and be able to stop putting himself down. To allow you to make a new creation of him in you, and be able to start new fresh relationship with his children. Give him your peace and the strength to move forward in his life. Have his children forgive him too for the past, and look forward to knowing their father better. Bring a real reconciliation between him and his children, in your merciful name I pray, amen.
