If one owned all the rich oil fields, all the giant skyscrapers, all the large ships, all the factories, all the silver and gold, all the land, and all the livestock, all the buildings, and all the houses, it would not equal the value of one soul. It is made in the image of God. It's value is seen in what it cost to redeem it. Winning souls is more important than feeding the hungry, sheltering the homeless, or providing health care for the sick. It is necessary and urgent because God's plan of salvation demands it.
Disciples are the vessels through which the gospel is to be carried to the lost.
Only the gospel will save men. People must hear and learn in order to come to Jesus. Christians are God's chosen instruments by which His word is taught, and we need to do our very best in this important task. D. God's work of the church requires it. It is the pillar and ground of the truth.
