What is Jesus’ main message? The gospel is the good, great and glorious news of salvation through Jesus Christ. Amen. If we look at all four gospels, the main theme is that Jesus spoke the most about the kingdom- in MT, MK &LK- and the Holy Spirit , in John. The Kingdom and the Spirit are the same: God Almighty and His presence and glory, through His Son Jesus the Christ, through the Holy Spirit. Amen! Glory to God forever! The kingdom, the gospel is the most glorious and important news in the universe for human beings. Pt 31 of The Anointing Series.
