What are the changes from “bad tree” to “good tree,” “put off” to “put on” regarding our speech? Foul language to wholesome speech. Complaining to trusting the Lord. Criticism to edifying remarks. Gossip to prayer. Deception to speaking truth. Angry words to kind words. Trivial blabbering to meaningful speech. Worldly philosophy to biblical truth. Praising self to praising God. It is words that resemble the heart changed by the Holy Spirit. Words that are thus loving, joyful, peaceful, patient, kind, good, faithful, gentle and self-controlled.
