Trinity in the Old Testament. Norman Gulley

In other words, how can a solitary God (OT) love as the Trinity does (NT)? Such assumed differences are not merely between law and grace, bondage and freedom, sovereign and free choice, but have to do with God Himself. If God relates to humans differently at any time and in any way, what does this do to His words “I the Lord do not change” (Mal 3:6)? Our presentation is confined to whether God is only solitary in the OT, compared to a Trinity in the NT.
