DAILY READINGS IN THE LIFE OF CHRIST - J.R. Miller (1890): 

June 20. Dropping Seeds

"It is like a grain of mustard seed, which, when it is sown in the earth, is less than all the seeds that be in the earth: But when it is sown, it groweth up, and becometh greater than all herbs, and shooteth out great branches; so that the fowls of the air may lodge under the shadow of it." Mark 4:31-32 

Many great histories of blessing — may be traced back to a very small seed. A woman whose name is forgotten dropped a Christian tract in the way of a man named Richard Baxter. He picked it up and read it, and it led him to Christ. He became a holy Christian, and wrote a book entitled, "A Call to the Unconverted," which brought many people to the Savior, and among others Philip Doddridge. Doddridge in turn wrote "The Rise and Progress of Religion," which led many into the kingdom of God, among them the great William Wilberforce. Wilberforce wrote, "A Practical View of Christianity," which was the means of saving a multitude, among them Legh Richmond. In his turn Richmond wrote the book called "The Dairyman's Daughter," which has been instrumental in the conversion of thousands.

The dropping of that one little tract seemed a very small thing to do; but see what a wonderful, many-branched tree has sprung from it! This is only one illustration of marvels of grace coming from the most minute grains of the heavenly seed. One seed planted in a heart, dropped by some very humble worker, perhaps unconsciously — may not only save a soul for an eternity of blessedness — but may start a series of divine influences which shall reach thousands of other lives. A simply invitation from his brother — brought Simon to Jesus; and what a tree sprang from that seed!

Let us go on, day by day, dropping seeds into as many hearts as we can. We may not always know what comes of them — but from any one of them may spring a history of blessing which shall reach thousands of souls. The branches of the tree from one seed may spread over all lands.
