Charles H. Spurgeon on Psalms 95:9

Your fathers tempted me. Though God cannot be tempted with evil he may justly be said to be tempted whenever men, by being dissatisfied with his dealings, virtually ask that he will alter those dealings, and proceed in a way more congenial to their feelings. If you reflect a little, you will hardly fail to perceive, that in a very strict sense, this and the like may be called tempting God. Suppose a man to be discontented with the appointments of providence, suppose him to murmur and to repine at what the Almighty allots him to do or to bear; is he not to be charged with the asking God to change his purposes? And what is this if it is not tempting God, and striving to induce him to swerve from his plans, though every one of those plans has been settled by Infinite Wisdom?

Or again, if any one of us, notwithstanding the multiplied proofs of Divine lovingkindness, doubt or question whether or not God do indeed love him, of what is he guilty, if not of tempting the Lord, seeing that he solicits God to the giving additional evidence, as though there was a deficiency, and challenges him to a fresh demonstration of what he has already abundantly displayed? This would be called tempting amongst men. If a child were to show by his actions that he doubted or disbelieved the affection of his parents, he would be considered as striving to extract from them new proofs, by asking them to evince their love more, though they may already have done as much as in wisdom and in justice they ought to do. And this is clearly tempting them, and that too in the ordinary sense of the term. In short, unbelief of every kind and every degree may be said to tempt God. For not to believe upon the evidence which he has seen fit to give, is to provoke him to give more, offering our possible assent if proof were increased as an inducement to him to go beyond what his wisdom has prescribed. And if in this, and the like sense, God may be tempted, what can be more truly said of the Israelites, than that they tempted God in Massah? ...We are perhaps not accustomed to think of unbelief or murmuring as nothing less than a tempting God, and therefore, we do not attach to what is so common, its just degree of heinousness. It is so natural to us to be discontented whenever God's dealings are not just what we like, to forget what has been done for us as soon as our wishes seem thwarted, to be impatient and fretful under every new cross, that we are scarcely conscious of committing a sin, and much less one more than usually aggravated. Yet we cannot be dissatisfied with God's dealings, and not be virtually guilty of tempting God. It may seem a harsh definition of a slight and scarcely avoidable fault, but nevertheless it is a true definition. You cannot mistrust God, and not accuse him of want either of power or of goodness. You cannot repine, no, not even in thought, without virtually telling him that his plans are not the best, nor his dispensations the wisest which he might have appointed in respect of yourselves. So that your fear, or your despondency, or your anxiety, in circumstances of perplexity, or peril, are nothing less than the calling upon God to depart from his fixed course —a suspicion, or rather an assertion that he might proceed in a manner more worthy of himself, and therefore, a challenge to him to alter his dealings if he would prove that he possesses the attributes which he claims. You may not intend thus to accuse or to provoke God whenever you murmur, but your murmuring does all this, and cannot fail to do it. You cannot be dissatisfied without virtually saying that God might order things better; you cannot say that he might order things better without virtually demanding that he change his course of acting, and give other proofs of his Infinite perfections. —Henry Melvill.
