For by your words you will be justified, and by your words you will be condemned.
Jesus tells us that we would be justified or condemned by our words. He does not say that we will be saved or condemned for what we do, or by our works, but by what comes out of our mouth. It is very common in humans speaking without thinking and, in such cases, we forget that words are like spilled water, which is very difficult to pick up and put back in its original container completely.
How we are justified by our words? When we confess with our mouth that Jesus is our Lord and we recognize Him as our only and sufficient Savior. One thief who was crucified alongside Jesus was a criminal his whole life; but in his last moment of life, he opened his mouth to acknowledge the Lordship of Jesus and the Word of God bears witness to his salvation. In contrast, the other thief was convicted by his own words, not his thief condition, because in that, both of them had the same history.
Let’s use our mouths to bless others, instead of cursing; but more important than that, let’s use it for salvation, acknowledging Jesus as our Lord and Savior. For Paul tells us in Romans 10:9-10: that if you confess with your mouth the Lord Jesus and believe in your heart that God has raised Him from the dead, you will be saved. For with the heart one believes unto righteousness, and with the mouth confession is made unto salvation.
In the natural world we know that when a policeman arrests a suspect of a crime he follows a protocol in which tells about the suspect’s rights. The policeman tells the arrested: “You have the right to remain silent, the right to hire a lawyer and anything you say can be used against you.” In other words, the suspect arrested could be judged based on his own words and they could incriminate the crime he is accused.
There is no single human being who can say he or she is innocent before God. All of us have sinned! If God had a heavenly police and He sent His angels to arrest us for our trespasses and sins, the protocol of arrest could well be what Matthew 12:37 says: For by your words you will be justified, and by your words you will be condemned. Facing a potential “divine arrest” we do not need to keep silent but say the right words.
As regards hiring an attorney, our problem is already solved, as 1 John 2:1 says: My little children, these things I write to you, so that you may not sin. And if anyone sins, we have an Advocate with the Father, Jesus Christ the righteous. We do not need someone else to intercede for us. Jesus Christ is seated at the right hand of God the Father as our defense attorney when we have fully trusted Him.
And so that our words are not used against us, when confronted by God do not justify our faults. Rather, let confess our sins, proclaiming Jesus as Lord of our lives and through Him we will receive salvation and eternal life. God bless you.
