Praying to receive what we are asking from God is the real prayers. I have witnessed people pray without receiving the answers to their prayers. Many people pray casually. Some people just do prayers as a religious practice. These kind of people have never received any answer from God. Prayer is a fruitful thing. It bears fruits. It is the thing that makes our working with God fruitful.
I want to pray to my Father in heaven and receive the answer to my prayers. I want to have a fruitful fellowship with God through prayers. So, I myself desires to receive the things that I ask of God. When we pray and God gives us what we are asking from Him, our hearts will be full of Jesus. No wonder that our Lord Jesus Christ told us to pray until our joy is full.
We should understand that there is the way we would pray before God can answer us. We should pray in faith. We have absolute believe in the ability of God that He is able to do whatsoever we are asking from Him. We should not have a wavering faith when we are praying. We should pray to God and believe that whatever we ask of Him, he is able to do it for us.
