“Keep this Book of the Law always on your lips; meditate on it day and night, so that you may be careful to do everything written in it.” Joshua 1:8
In prayer, the Word of God should be in our hearts and in our mouths. In our prayers we should use the Word of God and remind God of His promises to us -for our benefit not His. This builds our faith, and it also pleases God, because it is an expression of our confidence in His Word and His integrity.
This is a powerful form of prayer. Daniel found God's promise of the time of deliverance for God's people, and he prayed according to that (Daniel 9:2). His prayer acknowledged openly the truth of God's Word. Elijah's prayer for the heavens to be shut was based on the promise of God to do this if the people turned away from Him to worship idols (Duet. 11:16-17).
We should think on God's Word so that it might transform our hearts as it also renews our minds. Then we will be prepared to pray in faith.
Herbert Lockyer wrote, “The mightiest prayers are often those drenched with the Word of God.”
Since God's Word commands us to give constant attention to the Word and meditate on it night and day, it is clear that our praying should not be something separate from the Word, but that God's Word should direct our praying.
Father, thank You for Your Word and the truth it brings to bear on my life. Grant me the discipline to drench my heart and mind in Scripture so that I might be able to offer the mightiest of prayers to Your ears. In the wonderful Name of our Lord Jesus Christ, I offer this prayer, Amen.
