Jesus challenges us to mean what we say. Religious jargon and trite sayings are useless.
It is the power of the risen Master and Savior that means something. Jesus challenges us to understand what action God wants us to take not say some religious saying. The action Jesus took was always specific. He healed the blind but never exactly the same way.
God’s goal for us is that we speak plainly without the use of religious jargon.
May I live the life Jesus wants me to every day. May my life speak his power.
“Again, you have heard that it was said to our ancestors, You must not break your oath, but you must keep your oaths to the Master. But I tell you, don’t take an oath at all: either by heaven, because it is God’s throne; or by the earth, because it is his footstool; or by Jerusalem, because it is the city of the great King. Do not swear by your head, because you cannot make a single hair white or black. But let your ‘yes’ mean ‘yes,’ and your ‘no’ mean ‘no.’ Anything more than this is from the evil one. | Christian Standard Bible. (2020). (Mt 5:33–37). Nashville, TN: Holman Bible Publishers.
This is not the problem of “cursing,” but the challenge of using oaths to affirm that what is said is true. The Pharisees used all kinds of tricks to sidestep the truth, and oaths were among them. They would avoid using the holy name of God, but they would come close by using the city of Jerusalem, heaven, earth, or some part of the body.
Jesus taught that our conversation should be so honest, and our character so true, that we would not need “crutches” to get people to believe us. Words depend on character, and oaths cannot compensate for a poor character.
When there are many words, sin is unavoidable, but the one who controls his lips is prudent. (Prov. 10:19).
The more words a man uses to convince us, the more suspicious we should be. Jesus has a different way for us to live that the rest of the world. My word should be good enough. Others should know they can count on it.
