Prayer is done in man's time. Answer to prayer is done in God's time. You cannot "pray enough" to finally make God answer you. God is not ignoring you. God hears you from the start and has imparted the best answer for you, even before you ask, and at the very right moment, which only God in His infinite wisdom can know, the answer will come to you. Through the prophet Isaiah, in chapter 65 verse 24, God said, "I will answer them before they even call to me. While they are still talking about their needs, I will go ahead and answer their prayers!"
This is who the Father is to us! This is how He works.
Psalms 34:17-22 "The righteous cry out, and the Lord hears, and delivers them out of all their troubles. The Lord is near to those who have a broken heart, and saves such as have a contrite spirit. Many are the afflictions of the righteous, but the Lord delivers him out of them all. He guards all his bones; not one of them is broken. Evil shall slay the wicked, and those who hate the righteous shall be condemned. The Lord redeems the soul of His servants, and none of those who trust in Him shall be condemned. So I will respond as David did and say with him.... (34:1-3)
"I will bless the Lord at all times; His praise shall continually be in my mouth. My soul shall make its boast in the Lord; the humble shall hear of it and be glad. Oh, magnify the Lord with me, And let us exalt His name together. <3
