Romans 2:1: “You, therefore, have no excuse, you who pass judgment on someone else, for at whatever point you judge another, you are condemning yourself, because you who pass judgment do the same things.”
The word of God teaches us not to judge others. It actually does not give us any right to do that. It does not give anybody (non Christians included) to judge. The only one who righteously can take upon a position of a judge is God. He carries out judgment when He sees that fit to be done. And believe me, He is not that fast with judgment as we are. To tell the truth He is extremely patient. I can add that if a person has received Christ as his personal Lord and Savior, that person is no longer judged, because he has passed from darkness to light. God justifies him, not condemns.
People get into traps when they think that if they do something bad and judge others who do the very same things they will somehow avoid God’s judgment. On the contrary, by judging others we attract condemnation for ourselves. By condemning others we condemn ourselves. So, let us be careful when we want to pronounce a word of criticism against somebody. We might be on the path of self destruction. You need God’s mercy and the person you want to criticize also needs the very same thing. So, why do you want to take away the mercy of God from the person? You do not want anybody to take that away from you. So, let us be merciful.
God has given us a completely different mission. We were given the role of intercessors and those who proclaim the message of reconciliation. We have to preach that God is good and merciful and ready to forgive all of our sins. Even seeing that somebody sins we are taught to be patient and cover up the thing, not to expose it (in most cases). Why? Because we sin a lot too. We commit sins every day. And quite often we do not even realize that we do that.
We like categorizing sins: unpardonable, very big, big, medium size, small, very small. That is funny. God does not do that. Sin is sin. And He hates any kind of sin. However, He also forgives any kind of sin. His mercy precedes his judgment. That is his nature. Before judging somebody He always invites the person to accept mercy. And if the person does that God removes his judgment from the person. God forgives. Let us learn to be like him. Let us carry the message of reconciliation across the world and keep away from judgmental attitude that does more harm than good. Everybody has sinned and everybody needs forgiveness from God (including us Christians). Let us give to others what we want to get for ourselves: mercy, understanding and forgiveness. That is the real spirit of Christianity. It is unconditional love of Christ and mercy for everyone who accepts it. Do not judge.
