Men have not become Trappists merely out of a hope for peace in the next world: something has told them, with unshakable conviction, that the next world begins in this world and that heaven can be theirs now, very truly, even though imperfectly, if they give their lives to the one activity which is the beatitude of heaven.
That activity is love: the clean, unselfish love that does not live on what it gets but on what it gives; a love that increases by pouring itself out for others, that grows by self-sacrifice and becomes mighty by throwing itself away.
But there is something very special about the love which is the beatitude of heaven: it makes us resemble God, because God Himself is love. Deus caritas est. The more we love Him as He loves us, the more we resemble Him; and the more we resemble Him, the more we come to know Him.
