What this adds up to, then, is this: no more lies, no more pretense. Tell your neighbor the truth. In Christ's body we're all connected to each other, after all. When you lie to others, you end up lying to yourself.
Watch the way you talk. Let nothing foul or dirty come out of your mouth. Say only what helps, each word a gift.
Don't grieve God. Don't break his heart. His Holy Spirit, moving and breathing in you, is the most intimate part of your life, making you fit for himself. Don't take such a gift for granted.
Make a clean break with all cutting, backbiting, profane talk. Be gentle with one another, sensitive. Forgive one another as quickly and thoroughly as God in Christ forgave you.
