As I read your post, the thought that came into my head was, “You have an incredible weapon.” The weapon of prayer.
I have a family member that left home 2 years ago and couldn’t leave home fast enough. During this time we continued to pray and leave it with God. I cannot begin to tell you the things that happened and the changes we have seen that can only, only, be attributed to the work of God in answers to our prayers. Sometimes we look at each other and marvel at what has happened and is happening even now. These changes came about in our absence and without any “help” from us, whatsoever. It has been a long road, to be sure, but completely worth it.
You have the same weapon, and more importantly, the same God, who stands at the right hand of the needy one. Psalm 109.31 The One who is able to do infinitely more than all we ask or think. Ephesians 3.20
Praying for those you care about and lovingly modeling the kindness, grace and forgiveness of God towards them is a powerful weapon that no man or Beast can stand against.
Grace and peace,
