When we say we’re going to do something, and back it up with a promise, it’s giving the person we promised, assurance that we will do it. But, when we swear to it, that’s without a doubt, we will keep our promise.
Why do we swear at all? Usually it’s because we have put doubt in someones head, from something we said we would do, and didn’t do it. Let us practice daily, to stand to our word. To do what we say. Let your no be no, and your yes be yes.
Matthew 5:34-37 (KJV) – but I say unto you, Swear not at all: neither by heaven; for it is God’s throne: nor by earth; for it is his footstool: neither by Jerusalem; for it is the city of the great King. Neither shalt thou swear by thy head, because thou canst not make one hair white or black. But let your communication be yea, yea; nay, nay: for whatsoever is more than these cometh of evil.
