Time for a Biblical self-check-up. Did you make your decision on the matter biblically or not? Have you taken a stand or position without considering the truth? Did you diligently inquire, attempting to get the whole truth and nothing but the truth? Did you ask both sides or just listen to one witness? Did you allow both parties a fair trial and the ability to present their sides, or did you just accept the one-sided narrative? If you shared your unfair judgment with others, does that make you a false witness? It is up to you to take your own check-up.
