Charles H. Spurgeon on Psalms 78:18

And they tempted God in their heart. He was not tempted, for he cannot be tempted by any, but they acted in a manner calculated to tempt him, and it always just to charge that upon men which is the obvious tendency of their conduct. Christ cannot die again, and yet many crucify him afresh, because such would be the legitimate result of their behaviour if its effects were not prevented by other forces. The sinners in the wilderness would have had the Lord change his wise proceedings to humour their whims, hence they are said to tempt him. By asking meat for their lust. Would they have God become purveyor for their greediness? Was there nothing for it but that he must give them whatever their diseased appetites might crave? The sin began in their hearts, but it soon reached their tongues. What they at first silently wished for, they soon loudly demanded with menaces, insinuations, and upbraidings.
