Author Richard Strauss reminds us that God can do anything he wants to do. We found that by his own words when we saw God's promise to Abraham. God promised to make Abraham the father of a great nation, and naturally Abraham needed a son in order for that promise to come true. He thought Hagar’s child, Ishmael, was to be that son, but God told him that Sarah would bear a son named Isaac through whom the promise would be fulfilled. It was real odd, this promise of God because Abraham was ninety nine years old and Sarah was ninety, and humanly speaking there was no possible way they could have a son. But God helped them to believe it by the way He introduced Himself that day. "Now when Abram was ninety nine years old, the LORD appeared to Abram and said to him, ‘I am God Almighty; Walk before Me, and be blameless’” (Genesis 17:1).
With Abraham he proved that he is El Shaddai God Almighty, the God who can do anything He wants to do, even rejuvenate dead wombs and give babies to couples in their nineties!
He is almighty, all-powerful. That name is used forty-seven more times in the Old Testament and never of anyone but God. It has a New Testament equivalent, used ten times, which means literally "to hold all things in one’s power.” Scripture is punctuated with references to God’s omnipotence from beginning to end. He is the Lord strong and mighty (Psalm 24:8). Power belongs to Him (Psalm 62:11).
"Great is our Lord, and abundant in strength” (Psalm 147:5). He wants us to know Him as the God who is able to do anything.
