“Holy communion is the shortest and surest way to Heaven. There are others, innocence, for instance, but that is for little children; penance, but we are afraid of it; generous endurance of the trials of life, but when they come we weep and ask to be spared. Once for all, beloved children, the surest, easiest, shortest way is by the Eucharist. It is so easy to approach the holy table, and there we taste the joys of Paradise.”(St. Pope Pius X) If we truly share in the life of Jesus through the Eucharist and die in that state of life, we will be with God forever in eternity. That is the guarantee Jesus gives  us in the Gospel. "If you eat my Body and drink my Blood, you shall have life everlasting."
