"All the preaching in the world will not make men feel deeply the need of the perishing souls around them. Nothing will so arouse in men and women a self-sacrificing zeal as to send them forth into new fields to work for those in darkness. Prepare workers to go out into the highways and hedges. Do not call men and women to the great center, encouraging them to leave churches that need their aid. Men must learn to bear responsibilities. Not one in a hundred among us is doing anything beyond engaging in common, worldly enterprises. We are not half awake to the worth of the souls for whom Christ died. 8T 147.4"
"And the lord said unto the servant, Go out into the highways and hedges, and compel them to come in, that my house may be filled."
EGW directly references the imagery of going into the 'highways and hedges' to find workers, which is a clear allusion to Luke 14:23.
