Chapter 5—Proper Education of the Young The third angel is represented as flying in the midst of the heavens, showing that the message is to go forth throughout the length and breadth of the earth. It is the most solemn message ever given to mortals, and all who connect with the work should first feel their need of an education, and a most thorough training process for the work, in reference to their future usefulness; and there should be plans made and efforts adopted for the improvement of that class who anticipate connecting with any branch of the work. Ministerial labor cannot and should not be intrusted to boys, neither should the work of giving Bible readings be intrusted to inexperienced girls, because they offer their services, and are willing to take responsible positions, but who are wanting in religious experience, without a thorough education and training.

These young men might have been saved to the ministry through well- organized plans. If the churches in the different places do their duty, God will work with their efforts by his Spirit, and will supply faithful men to the ministry. CE 45.2"
"Then saith he unto his disciples, The harvest truly is plenteous, but the labourers are few;"
