The prayers in the Bible are surprisingly honest. There is praise and thanks, but also complaint, confusion, anger and grief; the Psalms are a whole book of them. “Pour out your heart before him,” says Psalm 62:8. You need no special words or place: Jesus says to go into your room, shut the door and pray to your Father “which is in secret.”
When one of His disciples asked, “Lord, teach us to pray,” Jesus gave them the Lord’s Prayer (Luke 11:1-4; Matthew 6:9-13). It is a pattern as much as a script: begin with God’s name and kingdom, ask for today’s bread, ask for forgiveness and give it, ask to be kept from evil. Paul adds thanksgiving to every request (Philippians 4:6) and says “Pray without ceasing,” which means keeping the conversation with God open through the day, not praying every minute.
What about prayers that seem unanswered? Jesus says, “Ask, and it shall be given you,” and in the same breath compares God to a father who gives “good things to them that ask him” (Matthew 7:11). John adds that we ask “according to his will” (1 John 5:14). Scripture is honest that the answer is sometimes not what we asked: Paul asked three times for his thorn to be taken away and it was not, and Jesus Himself prayed, “nevertheless not as I will, but as thou wilt.” An unanswered prayer is not a verdict on your faith or your worth.
And you do not pray alone. When we do not know what to ask, “the Spirit itself maketh intercession for us with groanings which cannot be uttered.” Jesus is present where two or three gather in His name, and James tells us to “pray one for another.” Asking someone to pray for you is part of how prayer is meant to work.
