Devouring words
In God’s sight our evil thoughts about others are bad enough, but thoughts have a habit of leading to words. For example, during Paul’s first missionary journey, when the Gentiles were beginning to show great interest in the gospel, the Jews ‘were filled with envy; and contradicting and blaspheming, they opposed the things spoken by Paul’ (Acts 13:45). Evil thoughts will of course never lead to good words, only evil ones.
James has much to say about the damage that our tongues can do. ‘Do not speak evil of one another, brethren … Who are you to judge another?’ (James 4:11–12). How easily judging others in our thoughts leads to criticizing them with our tongues. He later puts it in a slightly different way and adds the same ominous warning already seen above: ‘Do not grumble against one another, brethren, lest you be condemned. Behold, the Judge is standing at the door!’ (James 5:9).
Self-appointed judges and grumblers place themselves in a very dangerous position before Almighty God. But these are not the only things to banish from our mouths. Paul says, ‘Put off all these: anger, wrath, malice, blasphemy, filthy language out of your mouth. Do not lie to one another’ (Col. 3:8–9). Just as covetous thoughts about one another break the tenth commandment, so lying to one another breaks the ninth commandment.
