What does the Bible say about God's ability to answer prayer?

The Scriptures, particularly Ephesians 3:20-21, clearly express the boundless ability of God to fulfill our needs far beyond our expectations. Paul reminds us that God's power working within us enables Him to accomplish more than we can imagine. As Christians, we should approach Him in prayer with the confidence that He who created the universe is not limited in what He can do for us. Therefore, when we pray, we should do so believing that our prayers are being directed to a God who is indeed able to do wondrous things.
