When properly conducted, church schools will be the means of lifting the standard of truth in the places where they are established; for children who are receiving a Christian education will be witnesses for Christ. As Jesus in the temple solved mysteries which priests and rulers had not discerned, so in the closing work of this earth, children who have been rightly educated will in their simplicity speak words which will be an astonishment to men who now talk of “higher education.” CT 176.1
As the children sang in the temple courts, “Hosanna; Blessed is He that cometh in the name of the Lord” (Mark 11:9), so in these last days children's voices will be raised to give the last message of warning to a perishing world. When heavenly intelligences see that men are no longer permitted to present the truth, the Spirit of God will come upon the children, and they will do a work in the proclamation of the truth which the older workers cannot do because their way will be hedged up.

Our church schools are ordained by God to prepare the children for this great work. Here children are to be instructed in the special truths for this time, and in practical missionary work. They are to enlist in the army of workers to help the sick and the suffering. Children can take part in the medical missionary work and by their jots and tittles can help to carry it forward. Their investments may be small, but every little helps, and by their efforts many souls will be won to the truth. By them God's message will be made known and His saving health to all nations. Then let the church carry a burden for the lambs of the flock. Let the children be educated and trained to do service for God, for they are the Lord's heritage.—Testimonies for the Church 6:193-203.

The system of grading is sometimes a hindrance to the pupil's real progress. Some pupils are slow at first, and the teacher of these youth needs to exercise great patience. But these pupils may after a short time learn so rapidly as to astonish him. Others may appear to be very brilliant, but time may show that they have blossomed too suddenly. The system of confining children rigidly to grades is not wise. CT 177.1

The importance of the teacher's physical qualifications can hardly be overestimated; for the more perfect his health, the more perfect will be his labor. The mind cannot be clear to think and strong to act when the physical powers are suffering the results of feebleness or disease. The heart is impressed through the mind; but if, because of physical inability, the mind loses its vigor, the channel to the higher feelings and motives is to that extent obstructed, and the teacher is less able to discriminate between right and wrong. When suffering the results of ill health, it is not an easy matter to be patient and cheerful, or to act with integrity and justice. CT 177.2
