There is a thread that runs through most Bible stories. Someone is always underestimating God. The prophetess Deborah tells the Israelites that God has their back. They should fight against the Canaanite king and his general Sisera, who are keeping the nation hostage. People underestimate Deborah and Jael, because they are women. In doing so they underestimate God. God gives to Deborah the wisdom to lead the battle. God gives to Jael the strength to drive a tent peg through the sleeping head of General Sisera — you try lifting a sledge and using blunt stick to pierce a watermelon (Judges 4:21).
In Jesus’ famous story of the servants and the silver coins (called “Talents”), the servant with one talent underestimates the expectations the master has of him (Matthew 25:14-30). Jesus urges us to make use of whatever resources God has placed within us to serve his kingdom. Just because you can’t play cello like Yo Yo Ma or play ball like Michael Jordan, doesn’t mean that God doesn’t expect great things from you.
The ultimate story relating to people underestimating God is found in places like Zephaniah 1:7-18 and the book of Revelations. People always underestimate the Day of the Lord — not just how quickly it is coming, but how much they personally will be called to account for. There is a day coming when all who have ever lived on this planet will be called to judgement. The test question then we be, have we used the time and position that God has given us to do good and show compassion to our fellow man?
