Consider the work of former generations. During the lifetime of Jesus Christ the believing, firm souls were few and numbered, but the heavenly blessings descended so plentifully that in a number of years countless souls entered beneath the shadow of the Gospel. God has said in the Qur’án: “One grain will bring forth seven sheaves, and every sheaf shall contain one hundred grains.” [Qur’án 2:261] In other words, one grain will become seven hundred; and if God so wills He will double these also. It has often happened that one blessed soul has become the cause of the guidance of a nation. Now we must not consider our ability and capacity, nay, rather, we must fix our gaze upon the favors and bounties of God, in these days, Who has made of the drop a sea, and of the atom a sun.
