Jesus said to His disciples: “You have heard that it was said to your ancestors, do not take a false oath, but make good to the Lord all that you vow. But I say to you, do not swear at all; not by heaven, for it is God’s throne; nor by earth, for it is his footstool; nor by Jerusalem, for it is the city of the great King. Do not swear by your head, for you cannot make a single hair white or black. Let your ‘Yes’ mean ‘Yes’ and your ‘No’ mean ‘No.’ Anything more is from the evil one.”.

A believer ought to be honest in what they say and do and not require an artificial oath to follow through on their commitments. Likewise, the believer should live a life of integrity such that others trust them without seeking such oaths. Modern culture echoes that with phrases such as “that man’s word is his bond.” Seal the deal with a handshake. This is the ideal: if you say you will do it, you will, period. No oaths required.
