7 How great is the advantage of going out of the world, Christ Himself, the Teacher of our salvation and of our good works, shows to us, who, when His disciples were saddened that He said that He was soon to depart, spoke to them, and said, “If you loved me, you would surely rejoice because I go to the Father;” teaching thereby, and manifesting that when the dear ones whom we love depart from the world, we should rather rejoice than grieve. Remembering which truth, the blessed Apostle Paul in his epistle lays it down, saying, “To me to live is Christ, and to die is gain;” counting it the greatest gain no longer to be held by the snares of this world, no longer to be liable to the sins and vices of the flesh, but taken away from smarting troubles, and freed from the envenomed fangs of the devil, to go at the call of Christ to the joy of eternal salvation.
