We used to sing a song in church that said "Ah Lord God, thou has made the heavens and the earth by thy great power. Ah Lord God, thou has made the heavens and the earth by thy outstretched hand(arm)." Then we would get to the chorus and sing at the top of our voice the words that the Lord was trying to get us to understand..."nothing is too difficult for thee!" Nothing is too hard for the Lord!
I can get tired, want to quit, or stop prematurely. But God is omnipotent...He's all powerful. There is nothing that He cannot do. There is no situation that He cannot turnaround for your benefit. Jeremiah 32:27 says, “I am the Lord, the God of all the peoples of the world. Is anything too hard for me?"
The answer is emphatically NO! Trust the Lord today. Give Him that job situation...that relationship struggle...that ministry difficulty. Though its difficult for you we know the truth that His word says...NO-thing is too difficult for Him!
