The Assyrians surrounded Jerusalem and in response Hezekiah’s prayer focused NOT on his problems but on His God (See Isaiah 37:14-20).
the Hebrew God
the living God
the only God
the universal God
the creator God
Hezekiah’s prayer focused on both God’s greatness and God’s glory (see verse 20).
Don’t be problem focused in your praying, be God-focused. A similar prayer is found in Acts 4:24-30.
