When we tell God or anyone that we will do something, he expects us to keep our word. It doesn't matter what the cultural view of truth and lying or reliability is, we are to be honest before God and with each other. In a way, it is ridiculous to try to live in any other way. After all, God knows our hearts, our intentions, and our actions. He will hold us to our word whether anyone else does or not! So let's make sure our word is genuine and that we don't need to pile up a bunch of other "flowery" language, vows, or expletives — even ones normally acceptable in our culture — to prop up our commitments. If we say we'll do it, then let's do it!
