This is a series about the Trinity. It explores this doctrine by brief expositions of different passages from throughout the Gospel of Mark, showing how the Trinity is the explicit and implicit teaching and assumption of Scripture.
Throughout his letter, Mark has told us who Jesus is and, by extension, who God is. People have to believe in the real Jesus and the real God; you know — the triune One. If you don’t believe in the real Jesus, then you don’t have union with Christ, you don’t have salvation, you don’t know the Gospel, you aren’t reconciled to the Father and you don’t have the Holy Spirit. This means people have to actually understand and accept who He is.
They have to accept that He’s the eternal Son of God, sinless and holy. They have to believe He added a human nature to His divine nature, in the incarnation. They have to believe He and the Father are One, and that He and the Father are also distinct, in some way. They have to believe Jesus is equal to the Father in power and glory. They have to believe Jesus is co-eternal; He has no beginning or end. They have to believe Jesus is Lord of all, that He’s the rightful King over God’s creation, and that they must bow their knee to Him in submission like loyal subjects.
