Irreligion
Tempting God consists in putting his goodness and almighty power to the test by word or deed. Thus Satan tried to induce Jesus to throw himself down from the Temple and, by this gesture, force God to act. Jesus opposed Satan with the word of God: "You shall not put the LORD your God to the test." The challenge contained in such tempting of God wounds the respect and trust we owe our Creator and Lord. It always harbors doubt about his love, his providence, and his power.
