'Call to Me and I will answer you, and I will tell you great and mighty things, which you do not know.'
What a fantastic promise this is from God. That if we humble ourselves and pray to Him, He will answer us. God doesn't promise to answer the prayers of those who have no faith in Him. But He does promise to answer the prayers of the one who prays in faith, believing that God will answer. He may not answer as we request, but always will answer for our best and for His glory.
