Your faith is vain. 1Cor 15:14. The meaning of this passage here is, that their faith was vain, because, if Christ was not raised up, they were yet unpardoned sinners. The pardon of sin was connected with the belief of the resurrection of the Lord Jesus, and, if he was not raised, they were still in a state of sin.
Ye are yet in your sins. Your sins are yet unpardoned. They can be forgiven only by faith in him, and by the efficacy of his blood. But if he was not raised, he was an impostor; and, of course, all your hopes of pardon by him, and through him, must be vain.
