Derived from Michael Horton's recently released The Christian Faith, this digital short presents a full theological investigation into the biblical concept of union with Christ. Horton covers the nature of this union, exegetical development of the concept, and both historical visions and contrasting paradigms of it. He also draws connections between a Christian's ongoing union with his or her Savior and grace, ontology, essence and energies, and covenant—an altogether masterful sketch of a beautiful and mysterious spiritual reality.
