Simply "Yes" or "No"
Again, you have heard that it was said to the people long ago, ‘Do not break your oath, but fulfill to the Lord the vows you have made.’ But I tell you, do not swear an oath at all: either by heaven, for it is God’s throne; or by the earth, for it is his footstool; or by Jerusalem, for it is the city of the Great King. And do not swear by your head, for you cannot make even one hair white or black. All you need to say is simply ‘Yes’ or ‘No’; anything beyond this comes from the evil one. Matthew 5:33-37
People can and will say anything. We hate admitting that we're wrong, or that we don't know something. And even "news" these days is full of falsehood. Let's rise above the world to be like Jesus, and let's simply be honest people of our word.
