I was taught that the literal translation of, “Ask and you shall receive, seek and you shall find, knock and the door shall be opened…” (Matthew 7:7) is "Keep on asking, keep on seeking, keep on knocking…" There is an implied persistence in the words that Jesus spoke. Why? Perhaps because many things will only come to us through time, and as a result of our faithfulness to prayer, which is God’s desire. He has made a way for his children to receive many gifts, and that way is through prayer. It does not change God; it changes US.
Did you ever consider the hour Christ Jesus spent in the Garden at Gethsemane, before he was seized? His words to the Apostles were, “You should have been awake and praying not to be put to the test.” Have you ever experienced praying for an entire hour for one single purpose? It is very different from the quick hello-goodbye request that we too often submit to God in haste. One has to plunge into the depths of prayer to be able to really cry out to God, and it is a mark of our faithfulness to him if we are willing to pour our body, mind, and soul into our requests, time after time, with earnest. He rewards this perseverence with his many graces and mercies, and sometimes the direct answer to our prayers … sometimes, something even better.
