The devil thought that he could make Jesus test God on whether He would keep His promises,
“Then he brought Him to Jerusalem, set Him on the pinnacle of the temple, and said to Him, ‘If You are the Son of God, throw Yourself down from here. For it is written: “He shall give His angels charge over you, to keep you,” and, “In their hands they shall bear you up, lest you dash your foot against a stone.” And Jesus answered and said to him, ‘It has been said, “You shall not tempt the LORD your God”’” (Luke 4:9-12).
God will keep His promises. We do not have to do something to test Him to see whether He will do as He promised. We are not in the place to test Him. Remember, He is the Creator; we are the creatures.
