Many Bible heroes expressed doubts about God.
At the Red Sea, Moses cried out to God about the apparent hopelessness of his situation.
Job wondered why God allowed him to suffer so much.
David questioned why he should bother to endure distress righteously when he saw wicked men prosper.
Gideon doubted the veracity of God’s directive.
Jeremiah questioned God’s fairness.
While locked in prison, John the Baptist doubted whether Jesus was the Messiah.
Thomas, the apostle, questioned whether Jesus had risen from the dead.
God highlights the unbelief of these men, in part, to assure us that he is neither surprised nor offended by our doubts.
