My friend, your prayers has been answered by God already the first time you asked this prayer. Please understand that our timing is not the same as the Father. He knows exactly when, where, and what they will repent. God is still working through them and He is not finish with them yet. What we want happen right away, God may wait years for it to happened. Faith & patience are important to remember and not doubt. God bless you for praying for your friend.
