Psalm 81:10, “I am the LORD thy God, which brought thee out of the land of Egypt: open they mouth wide, and I will fill it.”
I believe God is saying here that He has brought us out of the world of sin into a new life of serving Him. He is saying to open our mouth wide so that He can fill our lives with blessings.
William Carey’s (famous missionary to India) motto was, “Expect great things from God. Attempt great things for God.” This is a really good goal for all of us. The 1828 dictionary defines the word ‘expect’ as: to look for; to wait for; to entertain a belief that an event will happen. When we are confident that God will work, then and only then, will we get out and attempt great things for Him. Sometimes we fail before we start because we do not expect God to work. What a powerless life this produces.
You need to think about your expectations of God. Do you expect Him to work greatly in your life? Do you expect Him to answer your prayers (even the impossible)? Do you expect souls to be saved when you present the Gospel to them? When you wake up in the morning, do you expect God to do great and mighty things through your life? (Jeremiah 33:3)
Is your mouth open wide to His blessings or are you limiting what He can do because of unbelief? If our blessings from God were determined according to how wide our mouth is open to receive them, I wonder how ‘blessingless‘ some of our lives would be. (Not sure that is a word, but I am sure you get the point.)
Start believing with your whole heart (open your mouth wide) that God wants to do great works (in your life, in your church, in your community, and in this world) and then step out to make them happen!
