More than anything else in the world, it is our tongues that get us into trouble. Words have the power to bring life, and the power to crush it, whether we say the wrong thing, say it the wrong way, or don't say anything when we know we should.
No man can tame the tongue, but God can redeem it, if you'll let Him. Learning this "hack" to life can save us from a lot of trouble and turmoil.
