The Kingdom Language Is Truth

But let your Yes be Yes, and your No, No. For whatever is more than these is from the evil one. (Matthew 5:37).

Jesus says that anything beyond a simple, truthful yes or no is "from the evil one" because of what it reveals about the heart and the influence behind it. In Jesus day, people used elaborate oaths to sound credible because their word alone couldn't be trusted. Jesus cuts through that and says, "If you're walking in truth, your word doesn't need reinforcement!"
