Praying Scripture is powerful. One great way to teach children to pray more powerfully is to teach them verses they can pray. I suggest you give them a list to keep in their prayer journals. Make sure they know how to pray each verse as you teach them the verses. Here are a few verses to start.
Ephesians 5:20 (ICB) Always give thanks to God the Father for everything, in the name of our Lord Jesus Christ.
Psalms 51:6 (ICB) Create in me a pure heart, God. Make my spirit right again.
Ephesians 1:17-20 (ICB) I always pray to the God of our Lord Jesus Christ—to the glorious Father. I pray that he will give you a spirit that will make you wise in the knowledge of God—the knowledge that he has shown you. I pray that you will have greater understanding in your heart. Then you will know the hope that God has chosen to give us. I pray that you will know that the blessings God has promised his holy people are rich and glorious. And you will know that God’s power is very great for us who believe. That power is the same as the great strength God used to raise Christ from death and put him at his right side in heaven.
John 15:5 (ICB) I am the vine, and you are the branches. If a person remains in me and I remain in him, then he produces much fruit. But without me he can do nothing.
Jeremiah 29:11 (ICB) I say this because I know what I have planned for you,” says the Lord. “I have good plans for you. I don’t plan to hurt you. I plan to give you hope and a good future.
Philippians 4:13 (NKJV) I can do all things through Christ who strengthens me.
1 John 5:14-15 (ICB) We can come to God with no doubts. This means that when we ask God for things (and those things agree with what God wants for us), then God cares about what we say. God listens to us every time we ask him. So we know that he gives us the things that we ask from him.
1 John 14:14 (ICB) If you ask me for anything in my name, I will do it.
Proverbs 18:10 (ICB) The Lord is like a strong tower. Those who do what is right can run to him for safety.
