The phrase used often by believers and non-believers is "Don't judge me!!" You have no right whatsoever! The reality is believers must show discernment. Immediately after Jesus says, “Do not judge,” He says, “Do not give dogs what is sacred; do not throw your pearls to pigs.” Jesus mentions in another portion of scripture, “Watch out for false prophets by their fruit you will recognize them.” The point is how are we to discern who are the “dogs”, “pigs” and “false prophets” unless we have the ability to discern and make righteous judgments on doctrines and deeds? Jesus has given us permission to tell right from wrong and we must be wise in the way we deal with people. When we look at forgiveness. The popular view being, "Forgiveness is for you." I would suggest that People should reconsider what Jesus has done for them. The grace and mercy God appoints to them should be given to others as well. You don't want to miss this conversation, you might have a different view once it's concluded.
