What does the Bible say about prayer?

“But you, when you pray, enter into your inner room, and having shut your door, pray to your Father who is in secret; and your Father who sees in secret will reward you openly.”

“Pray without ceasing.”

““Ask, and it will be given you. Seek, and you will find. Knock, and it will be opened for you.”

“In nothing be anxious, but in everything, by prayer and petition with thanksgiving, let your requests be made known to God.”

“Pray like this: “‘Our Father in heaven, may your name be kept holy. Let your Kingdom come. Let your will be done on earth as it is in heaven. Give us today our daily bread. Forgive us our debts, as we also forgive our debtors. Bring us not into temptation, but deliver us from the evil one. For yours is the Kingdom, the power, and the glory forever. Amen.’”

“Confess your sins to one another and pray for one another, that you may be healed. The insistent prayer of a righteous person is powerfully effective.”

“This is the boldness which we have toward him, that if we ask anything according to his will, he listens to us. And if we know that he listens to us, whatever we ask, we know that we have the petitions which we have asked of him.”

“In the same way, the Spirit also helps our weaknesses, for we don’t know how to pray as we ought. But the Spirit himself makes intercession for us with groanings which can’t be uttered.”
