Found 101 times in the New Testament, the Greek verb “dei” meant “must,” “has to,” “it is necessary.”
This word has been compared to a triangle since this shape “must” have three sides. Jesus said the Scriptures “must” be fulfilled (Mt. 26:54). He also said “it was necessary” for Him to suffer many things (Mk. 8:31). Worship “must” be in spirit and truth (Jn.
4:24). We “must” obey God when man’s laws conflict with those given by God (Acts 5:29). All “must” one day stand before the Lord in judgment (2 Cor. 5:10). To be saved a person “must” believe in God (Heb. 11:6). The first verse in the book of Revelation also has this term.
