Because it is contained in Scripture, "Behold, I lay in Zion a chief cornerstone, chosen, and precious: He who believes in him will not be disappointed."

 (ii) Christianity introduced a new attitude to work. It is the conviction of the New Testament that all work must be done for Jesus Christ. Paul writes: "Whatever you do in word or deed, do everything in the name of the Lord Jesus" ( Colossians 3:17). "Whether you eat or drink, or whatever you do, do all to the glory of God" ( 1 Corinthians 10:31). In the Christian ideal work is not done for an earthly master or for personal prestige or to make so much money; it is done for God. It is, of course, true that a man must work in order to earn a wage and he must work to satisfy a master; but beyond that there is for the Christian the conviction that his work must be done well enough to be able to show it to God without shame.
