God is a fair and generous judge

Praying always with all prayer and supplication in the Spirit. (Ephesians 6:18a KJV)

 We are meant to be persistent in our prayer lives. That means being tenacious, determined to pray, praying regularly, and continuing to pray in faith even if we don’t receive the answer quickly.
 Jesus is not seeking lengthy prayers or repetitious prayers. What is important is that our prayers are heartfelt communication with our Father who loves us.
 The idea of persistence in prayer isn’t that we are to try to wear God out with our asking over and over. We are to bring our requests before Him with faith and trust, knowing that He loves us like a father loves his child, and will give us what we ask for when it is good for us and within His will to do so. That being said, it should be understood that being persistent in prayer will not always result in God answering the way that we are asking.
 We shouldn’t lose faith if our prayers aren’t answered immediately. We’re told to not lose heart. Jesus instructs us to carry on in faith and confidence, knowing that God is a fair and generous judge, a loving father, who will answer according to His will and in His time.
 And perhaps most important of all to remember, God loves each of us as His children. He cares for us. He has our best interests at heart. We can and should come to Him in prayer with faith, trust, humility, and love for the One who loves us with His everlasting love. —Peter Amsterdam [1]

 Waiting on God requires the willingness to bear uncertainty, to carry within oneself the unanswered question, lifting the heart to God about it whenever it intrudes upon one’s thoughts. —Elisabeth Elliot
