All who desire an opportunity for true ministry, and who will give themselves unreservedly to God, will find in the canvassing work opportunities to speak upon many things pertaining to the future, immortal life. The experience thus gained will be of the greatest value to those who are fitting themselves for the ministry. It is the accompaniment of the Holy Spirit of God that prepares workers, both men and women, to become pastors to the flock of God. As they cherish the thought that Christ is their Companion, a holy awe, a sacred joy, will be felt by them amid all their trying experiences and all their tests. They will learn how to pray as they work. They will be educated in patience, kindness, affability, and helpfulness. They will practice true Christian courtesy, bearing in mind that Christ, their Companion, cannot approve of harsh, unkind words or feelings. Their words will be purified. The power of speech will be regarded as a precious talent, lent them to do a high and holy work. The human agent will learn how to represent the divine Companion with whom he is associated. To that unseen Holy One he will show respect and reverence because he is wearing His yoke and is learning His pure, holy ways. Those who have faith in this divine Attendant will develop. They will be gifted with power to clothe the message of truth with a sacred beauty. 2TT 541.1
There are some who are adapted to the work of the colporteur and who can accomplish more in this line than by preaching. If the Spirit of Christ dwells in their hearts, they will find opportunity to present His word to others and to direct minds to the special truths for this time. Men suited to this work undertake it; but some injudicious minister flatters them that their gifts should be employed in preaching instead of in the work of the colporteur. Thus they are influenced to get a license to preach, and the very ones who might have been trained to make good missionaries to visit families at their homes, to talk and pray with them, are turned away from a work for which they are fitted, to make poor ministers, and the field where so much labor is needed and where so much good might be accomplished is neglected. 2TT 542.1
