For to this end Christ both died, and rose, and revived, that he might be Lord both of the dead and living.

People's New Testament

14:9 For to this end Christ both died, and rose, and revived. The life of the Christian is a new life that springs out of Christ's death; we die with him; we rise with him (Ro 6:4).

That he might be Lord of the dead and living. Hence, since our life comes from him, and springs from his death and resurrection, these make him our Lord, whether we be living or dead.

Jamieson-Fausset-Brown Bible Commentary

9. For to this end Christ both, &c.-The true reading here is, To this end Christ died and lived ("again").

that he might be Lord both of the dead and-"and of the"

living-The grand object of His death was to acquire this absolute Lordship over His redeemed, both in their living and in their dying, as His of right.

Matthew Henry's Concise Commentary

14:7-13 Though some are weak, and others are strong, yet all must agree not to live to themselves. No one who has given up his name to Christ, is allowedly a self-seeker; that is against true Christianity. The business of our lives is not to please ourselves, but to please God. That is true Christianity, which makes Christ all in all. Though Christians are of different strength, capacities, and practices in lesser things, yet they are all the Lord's; all are looking and serving, and approving themselves to Christ. He is Lord of those that are living, to rule them; of those that are dead, to revive them, and raise them up. Christians should not judge or despise one another, because both the one and the other must shortly give an account. A believing regard to the judgment of the great day, would silence rash judgings. Let every man search his own heart and life; he that is strict in judging and humbling himself, will not be apt to judge and despise his brother. We must take heed of saying or doing things which may cause others to stumble or to fall. The one signifies a lesser, the other a greater degree of offence; that which may be an occasion of grief or of guilt to our brother.
