There are many reasons this is helpful and interesting but here’s what stuck out to me: In the entire sweep of biblical history covering hundreds of people and thousands of years, there are only 21 times God used dreams to communicate something. All but 6 of those times are in the Old Testament. Among those in the New Testament, 4 of 6 were to Joseph regarding his role with and protection of the Christ child.
Also, the majority of the dreams (perhaps all, depending on how you look at it) are given to move forward the history of redemption culminating in Christ. After the dream of Pilate’s wife, just prior to Christ’s crucifixion, no further examples of this kind of communication from God exist in scripture.
So what do we make of this?
One thing is, if I think God is communicating with me directly via a dream, I’m probably wrong. The instances of God communicating this way are so infrequent in scripture as to be statistically insignificant and seem to be reserved for those with a special role in God’s outworking of redemptive history. Dreams are never given just to convey information about personal life decisions or even for the purpose of evangelism.
However, there is one sure fire way to be sure we’re hearing from God and that is to be a student of His Word. The truth is we don’t need dreams or other extra-biblical communication from God in order to know and do His will. There is nothing we need to know to live a life pleasing to God that is not contained within the pages of the Bible.
All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness, that the man of God may be complete, equipped for every good work. – II Timothy 3:16-17
