I wrote this just now for a struggling mom and thought I would share here in case someone needs it:
“Now this is the confidence that we have in Him, that if we ask anything according to His will, He hears us. And if we know that He hears us, whatever we ask, we know that we have the petitions that we have asked of Him.” (1 John 5:14-15).
God hears us not because we FEEL He does or even because we THINK He does. He hears when we ask according to His will and mix it with faith; He hears you because it is His character and nature to do so.
Pretty sure asking for your child's salvation, healing, and deliverance, and for reconciliation of broken relationships IS according to His will. Whether His will comes to pass or not is up to the choices of the people involved. But God can be very persuasive. Think of the story of Jonah!
That being said, answering prayer is God's business and God's way. The Bible clearly says that in order to please God you must believe God, and that He is a rewarder of those who diligently seek Him. A double-minded person should not think they will receive anything from God. So the task at hand for us is to cultivate our faith so we are not double-minded.
God's time-table is not ours, usually. We are in need of ENDURANCE! There are other many verses flooding my mind right now, I wish I could share them all! My encouragement to you, sweet mother, is to make sure you're in a fantastic word-teaching church, and that you make it your life mission to know Him as intimately, closely as you can. He IS the answer, not the enemy. And as I am fond of reminding people, it takes as long as it takes for God to get folks to cooperate with Him, because of the free will He gave us. I have taken on the mantle of intercessor. If the Holy Spirit doesn't succeed in apprehending one, two, or all three of my boys, it's not because God didn't try or that He's not able, but because of their stubbornness.
I am now living quite well "in the meantime" and if you're interested in learning how to do that we can talk more off the platform. May God do as He says He will do---exceedingly abundantly over all you could think or ask. But you have to trust Him with your whole heart. You have to "see" with the eyes of faith.
