"Let not our young men be deterred from entering the ministry. There is danger that through glowing representations some will be drawn away from the path where God bids them walk. Some have been encouraged to take a course of study in medical lines who ought to be preparing themselves to enter the ministry. The Lord calls for more ministers to labor in His vineyard. The words were spoken, “Strengthen the outposts; have faithful sentinels in every part of the world.” God calls for you, young men. He calls for whole armies of young men who are large-hearted and large-minded, and who have a deep love for Christ and the truth. GW 63.2"
"Pray ye therefore the Lord of the harvest, that he will send forth labourers into his harvest."
EGW's call for more ministers directly reflects the principle in Matthew 9:38, where Jesus instructs his disciples to pray for laborers to be sent into the harvest. Both passages emphasize the need for more individuals to dedicate themselves to ministry.
"Also I heard the voice of the Lord, saying, Whom shall I send, and who will go for us? Then said I, Here am I; send me."
Both passages involve a call to service. EGW's passage is a call to young men to enter the ministry, while Isaiah 6:8 is Isaiah's response to God's call. The underlying theme of responding to a divine call is present in both.
"The measure of capacity or learning is of far less consequence than is the spirit with which you engage in the work. It is not great and learned men that the ministry needs; it is not eloquent sermonizers. God calls for men who will give themselves to Him to be imbued with His Spirit. The cause of Christ and humanity demands sanctified, self-sacrificing men, those who can go forth without the camp, bearing the reproach. Let them be strong, valiant men, fit for worthy enterprises, and let them make a covenant with God by sacrifice. GW 63.3"
"Let us go forth therefore unto him without the camp, bearing his reproach."
The EGW passage directly quotes and applies the concept of 'bearing his reproach without the camp' from Hebrews 13:13.
