The Christian’s language must be godly and reflect a heart consecrated for God. Paul commanded the Ephesians to let no corrupt communication proceed from their mouths but rather words of edification and grace, Ephesians 4:29. He wrote the Colossians to walk wisely around worldly people and to speak gracefully and thoughtfully, Colossians 4:6. He told Titus to encourage the young men to have sound speech that could not be condemned, Titus 2:8.
Our words must encourage and edify all men, especially our brethren. Our speech must be graceful, or beautiful. We must speak words of kindness. When we must speak tough words, such as words of rebuke, we must still speak with grace and love, Ephesians 4:15.
Our words can comfort the downhearted, 1 Thessalonians 5:14. Too many brethren suffer without a word of exhortation from loving brethren. We pray for these individuals but we should also call or send a card to show our concern. Since we have been comforted by God, we should comfort others, 2 Corinthians 1:4.
Christians must always be ready always to give a defense of our faith, with a meek and fearful spirit, 1 Peter 3:15. Proverbs 15:28: “The heart of the righteous studies how to answer, but the mouth of the wicked pours forth evil.” Christians must study the word to prepare a scriptural defense of his belief. A foolish person, on the other hand, will answer “my church believes…,” or “my preacher says…,” or “I think…” We cannot answer the world in its folly. We must know why we believe what we believe and be able to defend it with scripture. When we do this, we will take our tongue, that unruly evil, and use it for good.
