Proverbs 12:17 KJV — He that speaketh truth sheweth forth righteousness: but a false witness deceit.
When you speak the truth, you show God’s way of doing things.
When you speak anything else, you are a false witness and a manifestation of deceit.
Your testimony as a witness is measured by whether or not it’s based on the truth (ie the word of God) or not.
Speak the truth.
