‘Abdu’l-Bahá beautifully tells us how the days that are without pain and suffering in the path of the Blessed Beauty just pass by fruitlessly. When a believer feels the pain and suffering when making the calculations and contributions for the Right of God, then the believer can relax, knowing what ‘Abdu’l-Bahá says. But there is no pain in relaxing, so we make more sacrifices.
