Model your prayers after those you find in Scripture.
Here’s an example based on Colossians 1:9-10. “Fill my friend with the knowledge of your will. Give spiritual wisdom and understanding. Help him to walk worthy of you, please you, bear fruit in every good work and know you more every day.”
I read: Carefully determine what pleases the Lord. . . .understand what the Lord wants you to do (Ephesians 5:10,17).
I wondered: How do I know what God wants?
Then I read: Ask God to give you complete knowledge of his will and to give you spiritual wisdom and understanding. Then the way you live will always honor and please the Lord (Colossians 1:9-10)
Now I know: Through prayer I know God’s will.
