13 What then is that full and perfect liberty in the Lord Jesus, who said, “If the Son shall make you free, then shall you be free indeed;” and when shall it be a full and perfect liberty? When enmities are no more; when “death, the last enemy, shall be destroyed.” “For this corruptible must put on incorruption, and this mortal must put on immortality.— And when this mortal shall have put on immortality, then shall be brought to pass the saying that is written, Death is swallowed up in victory.
O death, where is your struggle?” What is this, “O death, where is your struggle”? “The flesh lusts against the spirit, and the spirit against the flesh,” but only when the flesh of sin was in vigor. “O death, where is [now] your struggle?” Now shall we live, no more shall we die, in Him who died for us and rose again: “that they,” he says, “who live, should no longer live unto themselves, but unto Him who died for them and rose again.” Let us be praying, as those who are wounded, for the physician; let us be carried into the inn to be healed.
For it is He who promises salvation, who pitied the man left half-alive on the road by robbers. He poured in oil and wine, He healed the wounds, He put him on his beast, He took him to the inn, He commended him to the innkeeper's care. To what innkeeper? Perhaps to him who said, “We are ambassadors for Christ.” He gave also two pence to pay for the healing of the wounded man. And perhaps these are the two commandments, on which hang all the law and the prophets. Therefore, brethren, is the Church also, wherein the wounded is healed meanwhile, the traveller's inn; but above the Church itself, lies the possessor's inheritance.
