We have manifold references in Scripture to believers bitterly complaining and almost accusing God of unfairness or harshness. We sometimes look at these instances and think, “Well, if Moses can do it, if Job can do it, then it must be my prerogative as a Christian to voice my bitterness and complaints.”
We need to notice not just the complaints the biblical saints sometimes make, but the responses God gives.
But we need to notice not just the complaints the biblical saints sometimes make, but the responses God gives. Let’s take Job’s complaint as an example. As Job struggled with his afflictions, he found it impossible not to grumble that God would let one as righteous as he was suffer so greatly. Eventually, however, God answered Job’s complaints with stern words: “Who is this who darkens counsel by words without knowledge? Now prepare yourself like a man; I will question you, and you shall answer Me” (Job 38:2–3). What did Job say? Did he continue to complain? No. Instead, he declared: “I have uttered what I did not understand, things too wonderful for me, which I did not know... Therefore I abhor myself, and repent in dust and ashes” (42:3b, 6). He was severely rebuked for the attitude that he expressed to God. Likewise, Habakkuk the prophet complained bitterly that God was not being just by allowing wickedness to go unchecked. He demanded an answer from God, and when God gave it, Habakkuk said, “My body trembled; my lips quivered at the voice; rottenness entered my bones; and I trembled in myself” (Hab. 3:16a).
It is never proper to accuse God of wrongdoing.
It’s vital that we understand prayer in terms of the qualifications that are found throughout the Bible. By considering the scope of the Bible’s teaching on this subject, we may conclude that it is acceptable to bring all our cares to God, including matters that may move us to frustration or anger. However, we must not come to God in a spirit of complaint or anger against Him, for it is never proper to accuse God of wrongdoing.
