Have you ever been absolutely sure about something, only to find out you were wrong? Maybe, it was the name of the band that sang your favorite song or the name of the third baseman on your favorite team when you were in elementary school. Sometimes, the stakes are higher and being wrong more costly than that.
Erik Larson’s book, Isaac’s Storm: A Man, A Time, and the Deadliest Hurricane in History, is about a man and an entire bureau’s certainty that cost probably 6,000 their lives. And because they were so certain that a hurricane could not strike Galveston, Texas, a lot of people made fatal choices based on their own certainty—they were certain of houses that would stand, trains and tracks that would get them to their destinations, and that the slope of the coast would deter tidal waves and storm surges. Yet, in September, 1900, on Saturday and Sunday, probably the worst hurricane in modern history struck the exposed, helpless booming Texas city.
Some have been so certain about spiritual matters, but were wrong. They have been certain about what to bring God to worship (Gen. 4:2-3), about how to be saved from death (2 Kings 5:11-12), and about how to carry out God’s command (1 Sam. 15:13ff).
In the Sermon on the Mount, Jesus speaks of some who seemed certain, but were certainly wrong. Depicting the Judgment scene, Jesus preaches, “Not everyone who says to Me, ‘Lord, Lord,’ will enter the kingdom of heaven, but he who does the will of My Father who is in heaven will enter. Many will say to Me on that day, ‘Lord, Lord, did we not prophesy in Your name, and in Your name cast out demons, and in Your name perform many miracles?’ And then I will declare to them, ‘I never knew you; depart from Me, you who practice lawlessness’” (Mat. 7:21-23). These folks will have done religious acts in Jesus’ name. They will haven been certain they were on the right path, but Jesus says they will have been mistaken. They will not have done the will of the Father.
How many people will this ultimately describe? They have confidence in a preacher, a teaching, a tradition, a feeling, or a belief. Sadly, they have not even questioned whether or not it might not be what the Bible says on the matter. Jesus ends His sermon by talking about storms. This storm is more powerful than the one Larson writes about. It determines destiny (Mat. 7:24-27). We must base our certainty on the Rock!
