Only through Christ has immortality been made possible; He is the "author of (eternal) life" (Acts 3:15 A.V. mg.) - "the author of eternal salvation unto all them that obey him" (Heb. 5:9).
Yeye ni "Mkuu wa uzima (wa milele)" (Mdo. 3:15) - "(Mkuu) sababu ya wokovu wa milele kwa wote wanaomtii" (Ebra. 5:9).
