Prophecy involves speaking the mind of God under divine inspiration. Effective prophecy will be in line with scripture, glorify Jesus, edify and not divide, love sinners but hate sin, convict without condemnation, present God as the solution, not be controlling, stand the test of time, be tested, be a sign to unbelievers, exhort and comfort others, and be given according to the speaker's faith. Prophecy should build up the body of Christ.
