Question: "Is it really true that ALL things are possible with God?"
Answer: While God can do anything He wishes to do, God will not do things that would be against His holy will or are contradictory to His purposes. He can commit no sinful act, for example, for He is 100 percent holy, and sinning is not in His makeup.
However, the question may still seem to be reasonable to some, for with an omnipotent deity anything should be possible. An example may help to clear up any remaining doubt: “Can God make a stone so heavy He can’t lift it?” This question contains a paradox: if the Lord is so powerful He can make a stone of infinite weight, how would it not be possible, given His mighty power, for Him to lift it? Yet, since the stone is of infinite weight, how would it be possible for Him to lift it? The answer is that God will not deny Himself, which is the case here. It seems He would not even consider such an idea, for He would be pitting Himself against Himself, a foolish act having no value in His kingdom purposes.
It is worth noting that we see throughout the Bible that God is omnipotent—all-powerful—not equaled or surpassed by anyone or anything. In discussing God’s making a dry path in the mighty Jordan River to allow the safe passage of His people (a miracle, indeed), Joshua 4:24 says, “He did this so that all the peoples of the earth might know that the hand of the LORD is powerful and so that you might always fear the LORD your God.” In a similar vein, Jeremiah 32:26-27 relates, “Then the word of the Lord came to Jeremiah: ‘I am the LORD, the God of all mankind. Is anything too hard for me?’” Continuing, in Hebrews 1:3, we see, “The Son is the radiance of God’s glory and the exact representation of His being, sustaining all things by His powerful word.” These verses plus others show that all things within God’s will are possible for Him.
The angel in Luke 1:36-37 said, “Even Elizabeth your relative is going to have a child in her old age, and she who was said to be barren is in her sixth month. For nothing is impossible with God.” Some ask that if "nothing is impossible with God," does that mean I can run faster than a car or leap a tall building in a single bound? It is perfectly within God's power to make those things possible, but there is nothing in Scripture that indicates it is God's desire to make them possible. Something being possible for God does not obligate Him to actually do it. That is why we must be thoroughly familiar with Scripture, so that we can know what is God's desire and what He has promised, and thereby, know what God will make possible in our lives.
When we consider all of our heavenly Father’s mighty supernatural works throughout the Bible, we see that He indeed is capable of moving human events along the continuum of time, in spite of things seemingly impossible, all for His glorious purposes.
