Uncovering, making plain what was not known before. The word may be used of something God makes known during a church service (1Cor. 14:26), but more usually it has to do with something on a larger scale, like Gods righteousness, wrath (Rom. 1:17-18), or righteous judgment (Rom. 2:5). It may be used to describe a book (Rev. 1:1). God reveals things through the Spirit (1 Cor. 2:10). The gospel is not something people have made up but has been revealed by Christ (Gal. 1:11-12). The fullness of revelation awaits the return of Christ (2 Thess. 1:7; 1 Peter 1:13).
