Verses from Bible used to support Trinity – Three in 1 God:
The following are clear explanations of the verses in the Bible that Trinitarians have sometimes used in attempts to “prove” the Trinity and to substantiate that Jesus is God. Since there are an overwhelming number of very clear verses about Jesus Christ’s identity and his distinction from God, and since God’s Word has no contradictions, these comparatively few verses must fit with the many clear verses, and they do.
