The Lord tells us in Ephesians what we are to do with our speech:
1. Testimony. "Speaking the truth in love" (Eph 4:15).
2. Test of conversion. "Put off…former conversation" (Eph 4:22).
3. Thinking of others. "Speak every man truth with his neighbour" (Eph 4:25).
4. Thoroughness. "No corrupt communication proceed out of your mouth" (Eph 4:29).
5. Tattling to be done with. "Evil speaking be put away" (Eph 4:31).
6. Trifling to be put away. "Foolish talking…not to be named" (Eph 5:4).
7. Thankfulness. "Speaking…psalms," &c. (Eph 5:19).
