What, then, shall we do? How ought we to proceed when, in the words of the Gospel, the harvest is great in our country (i.e., many remain unconverted to Jesus Christ)? “Pray to the Lord of the harvest,” Jesus Himself teaches us [Mt. 9:38]. Thus, first and foremost, we must pray. If even in everyday matters people fall back upon prayer – asking God’s blessing at the beginning of some work and then throughout asking for renewal and strengthening of the work’s might (where prayer means nothing more than help), here, in the matter of conversion, prayer becomes the means itself – and a most effectual of means, for without prayer one cannot expect success even under the most perfect of circumstances.
Thus, it is not our missionaries alone who must pray; no, we their brethren must further their work by our own prayers. And what ought we to pray for? First, that the Lord will send workers into His harvest; second, that He will open the hearts of those who listen to the Word of the Gospel; third, that He will increase our Society’s numbers more and more; and finally that He will strengthen and confirm in us the desire we all now feel to further this work to the attaining of our goal.
