First, do not give the devil a foothold (25-28). Satan wants to infect the body of Christ, through the weak link. So we must not give him a foothold by lying to each other, dwelling in anger, or becoming lazy and stealing. Instead, as a healthy body, speak truthfully, deal with anger properly, and work hard with our hands to share with those in need. Second, forgive each other (29-32). Our mouths speak words that impact others. So we should only speak what is helpful for building others up according to their needs, not our benefit. How we treat another pleases or grieves the Holy Spirit of God, so we need to get rid of all that displeases him, and instead follow God's example. God has been so kind and compassionate, forgiving our sins in Christ. In obedience to the Holy Spirit, let's do so as well.
Application: Lord, help me to please your Spirit, especially in the way I treat your holy people, the words that come from my mouth, and in forgiving as you forgave me in Christ.
One Word: Love others; please God
