17 Of this divine charity, possibly nobody has spoken more excellently, more profoundly, or more earnestly than Bernard: "The reason for loving God," as he says, "is God; the measure of this love is to love without measure." "Where there is love, there is no toil, but delight." He admits having experienced this love himself when he writes: "O holy and chaste love! O sweet and soothing affection! . . . It is the more soothing and more sweet, the more the whole of that which is experienced is divine. To have such love, means being made like God." And elsewhere: "It is good for me, O Lord, to embrace Thee all the more in tribulation, to have Thee with me in the furnace of trial rather than to be without Thee even in heaven." But when he touches upon that supreme and perfect love whereby he is united with God Himself in intimate wedlock, then he enjoys a happiness and a peace, than which none other can be greater; "O place of true rest. . . For we do not here behold God either, as it were, excited with anger, or as though distracted with care; but His will is proved to be 'good and acceptable and perfect.' This vision soothes. It does not frighten. It lulls to rest, instead of awakening our unquiet curiosity. It calms the mind instead of tiring it. Here is found perfect rest. God's quiet quietens all about Him. To think of His rest is to give rest to the soul."
