So the captain came to Jonah, and said to him, "What do you mean, sleeper? Arise, call on your God; perhaps your God will consider us, so that we may not perish." At this point the captain (who probably worshiped Baal and Yamm, god of the sea) has more faith than Jonah.
Murmuring or complaining is one of those sins that are overlooked. Sometimes we get so focused on the "big sins" such as murder and adultery that we overlook this sin — but the Lord doesn't give this sin a free pass — quite the opposite. It's a hidden killer! This sin unleashed a plague that killed thousands of Israelites! [Numbers 16]
When the twelve spies were sent into Canaan to spy out the land, ten returned with a bad report. Their assessment was that it was impossible to conquer the land that God had promised them. Forgetting how God had led them with a pillar of fire by night, and fed them manna from heaven during the day, brought forth water out of a rock, and parted the Red Sea, they saw the situation with only their natural eyes, failed to walk by faith, and succumbed to fear.
When Ruth pledged her alligence to Naomi and to the God of Israel, it wasn't based on, "What ifs?" or circumstances. It was a faith rooted in her devotion to Naomi and God even to the point of death!
We have seen that names have significant meanings, and as discussed earlier, Elimelech, whose name means "My God is King", left Bethlehem with Naomi his wife and their two sons. The birth of these two boys must have brought joy and happiness, yet, having perished in Moab actually caused their very names to lose their original meanings.
