“But you, beloved, ought to remember the words that were spoken beforehand by the apostles of our Lord Jesus Christ” (Jude 17).
When we say, “This is what I think you ought to do,” it is being offered as an opinion or option. Scripture, however, uses “ought” to emphasize expectation, duty, responsibility. For instance, we ought to pray and not lose heart (Lk.18:1). We ought to keep calm and do nothing rash (Acts 19:36). We ought to love one another (1 John 4:11). Give heed to the oughts of scripture. In them you find what we ought to know, believe, and do.
