"If my prayers were truly aligned with God's will, He would answer—so this must not be His will."
How it sounds in your head: I've prayed, nothing happened, so obviously I'm asking for something outside God's plan. Maybe I need to accept this as His sovereign no. People say 'if it's God's will' for a reason—maybe it's just not His will for me.
"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 5:14-15Religious doctrine using 'God's will' as explanation for unanswered prayer instead of pointing to covenant promises.
When nothing changes despite prayer, 'God's mysterious will' becomes the spiritual explanation that stops you from questioning further. It sounds humble and surrendered.
Friends brought a blind man to Jesus. Jesus spit on his eyes, laid hands on him—the man saw partially, still blurry. Did Jesus say 'Must not be God's will for full healing'? NO. He laid hands on him AGAIN until he saw CLEARLY. Jesus persisted until COMPLETE breakthrough manifested.
I REFUSE the lie that God's will is a mystery I must decode through trial and error. IT IS WRITTEN that it IS His will for me to prosper and be in health. His will was REVEALED in Jesus, who healed ALL who came to Him. IT IS WRITTEN that I am blessed with EVERY spiritual blessing in heavenly places in Christ—the blessings are ALREADY MINE by covenant. The Abrahamic BARAK is God's declared will over my life, purchased by Jesus' blood. I don't hope it's His will—I KNOW it is because He WROTE IT DOWN. I stand on covenant, not confusion.
Your Father's will isn't a guessing game—He SHOWED you His will in Jesus, who never turned anyone away. The Father who prepared the party for the prodigal didn't have a 'mysterious will' that might exclude restoration—His will was ALWAYS the son's return and blessing.
