I will pray - and though not comforting may explain why he isn't listening:
Lu 11:24 When the unclean spirit is gone out of a man, he walketh through dry places, seeking rest; and finding none, he saith, I will return unto my house whence I came out.
25 And when he cometh, he findeth it swept and garnished.
26 Then goeth he, and taketh to him seven other spirits more wicked than himself; and they enter in, and dwell there: and the last state of that man is worse than the first.
2Pe 2:20 For if after they have escaped the pollutions of the world through the knowledge of the Lord and Saviour Jesus Christ, they are again entangled therein, and overcome, the latter end is worse with them than the beginning.
21 For it had been better for them not to have known the way of righteousness, than, after they have known it, to turn from the holy commandment delivered unto them.
22 But it is happened unto them according to the true proverb, The dog is turned to his own vomit again; and the sow that was washed to her wallowing in the mire.
My prayers for Mike to return to God as did the son who took his inheritence and wasted it then returned. Heavenly Father I pray that you will send ministering angels to Mike to minister him back into the paths of righteousness. I pray Mike will return to the family of God and repent of his earthly ways that would lead to condemnation.
I pray too Father for the family of Mike as they need your protection, wisdom and courage to stay the course while Mike is setting a bad example for the children. Let your Holy Spirit move to bring him back.
Thank you Father in Jesus name. I nothing is impossible with You. Thank you for answered prayers. Amen.
