To Challenge God
Exod 17:7 (NIV) And he called the place Massah {[7] Massah means testing.} and Meribah {[7] Meribah means quarreling.}because the Israelites quarreled and because they tested the LORD saying, "Is the LORD among us or not?"
Acts 15:10 (NIV) Now then, why do you try to test God by putting on the necks of the disciples a yoke that neither we nor our fathers have been able to bear? 11 No! We believe it is through the grace of our Lord Jesus that we are saved, just as they are."
