James 5:12 "Let Your Yes Be Yes"
Let Your Yes Be Yes
Some people think this prohibits them from taking oaths in a courtroom, or from taking an oath of allegiance. Their desire to obey God’s Word is admirable; but I submit they have really not understood it. As usual, Jesus is preaching in antithetical fashion; and it is important to discover just what he is saying before we take his statement with such insensitive absoluteness.
It needs to be noticed, first, that the Old Testament does permit men to take oaths, even oaths in God’s name. “You shall fear the Lord your God. Him you will serve, to him you will cleave, and you will swear by his name” (Deut. 10:20). Even in the New Testament, Paul, for example, regularly swears by God’s name.
