Not only should we build up our fellow believers, we need to ensure all the words flowing from our mouths point others to Christ. One of the best thermometers we give nonbelievers to measure our walk with Christ is what comes out of our mouths. It says in James 1:26 (CSB), “If anyone thinks he is religious without controlling his tongue, his religion is useless and he deceives himself.” Fighting over politics and posting mean memes online, no matter how true it may seem, does not bring others to the heart of God. If anything, it pushes others away.
Today, at work, school, or spending time with your family, ask God to help you with your tongue. Ask that all the communication that flows from you, whether in speech or on the internet, is pure and points people to Him. Pray for your fellow believers, and build them up whenever you can.
