God’s unlimited power
Can God create a rock so heavy that he can't lift it? I have heard this question several times before, and it seems self-contradictory, because since God is all-powerful he should be able to both make the rock and lift it.
You are correct in noting that this question is self-contradictory and illogical. Atheists have long asked this question to try to force Christians to concede that there is something incomplete about either God’s creative power or his providential power.
God’s power cannot be limited by self-contradictory and illogical questions. The Bible explains that God’s power is unlimited. When God appeared to Abram, he identified himself this way: “I am God Almighty” (Genesis 17:1). The psalm writer explained: “The Lord does whatever pleases him, in the heavens and on the earth, in the seas and all their depths” (Psalm 135:6).
God’s unlimited power is just one of many attributes that separates God from people. In the context of salvation, Jesus said, “What is impossible with man is possible with God” (Luke 18:27). Thank God that he has unlimited power and boundless love (John 3:16).
