that act of divine grace by which we are joined to Christ; and is considered, 1. As virtual, or that which was formed from all eternity (Ephesians 1:4); 2. Vital, or spiritual, formed in the moment of our regeneration (John 17:26; 1 John 4:13). It is represented in the Scripture by the strongest expressions language can admit of, and even compared to the union between the Father and the Son (John 17:11; John 17:21, etc.). It is also compared to the union of a vine and its branches (John 15:4-5); to the union of our food with our bodies (Ephesians 6:56, 57); to the union of the body with the head (Ephesians 4:15-16); to the conjugal union (Ephesians 5:23; Ephesians 5:30); to the union of, a king and his subjects (Matthew 25:34; Matthew 25:40); to a building (1 Peter 2:4-5; Ephesians 2:21-22). It is also represented by an identity or Sameness of spirit (1 Corinthians 6:17); by identity of body (1 Corinthians 12:12; 1 Corinthians 12:27); by an identity of interest (Matthew 25:40; John 20:17). This union must be considered, not as a mere mental union only in comfort or notion; nor a physical union, as between the head and the members; nor as an essential union, or union with the divine nature; but as a mystical union (Ephesians 5:32); an honorable union (1 John 3:1-2); a supernatural union (1 Corinthians 1:30); holy (1 John 3:24); necessary (John 15:4); inviolable (Romans 8:38-39). Some state it, thus: 1. A union of natures (Hebrews 2:11); 2. Of actions, Christ's obedience being imputed to us, and our sins reckoned to him (2 Corinthians 5:21); 3. Of life (Colossians 3:4), 4. Of sentiment (2 Corinthians 5:17); 5. Of interest (Matthew 25:34, etc.); 6. Of affection (2 Corinthians 5:14); 7. Of residence (John 17:24). The advantages of it are knowledge (Ephesians 1:18), fellowship (1 Corinthians 1:9), security (John 15) felicity (1 Peter 1:8), spirituality (John 15:8); and, indeed, all the rich communications of spiritual blessings here and hereafter (Colossians 1:22). The evidences of union with Christ are: light in the understanding (1 Peter 2:9); affection to him (John 14:21); frequent communion with him (1 John 1:3); delight in his word, ordinances, and people (Psalms 27:4; Psalms 119); submission to his will, and conformity to his image (1 John 2:5).
