"Able to save" means something more than just delivering men from hell. "Able to save" is the whole work of salvation from the first conviction of sin to complete glorification. Christ is not only able to save" those who REPENT, but He is able to make men repent. Christ is not only "able to save" those who BELIEVE, but He is able to give a new heart and work faith in men. Christ is not only "able to save" those who CONTINUE IN THE FAITH, but He is able to keep us from falling and give us a holy desire to be like Him.
