“And you know, one of the things, I know you’ve experienced this many of you, one of the things that happens when you become a Christian is – it’s amazing how the Lord sort of changes the things you talk about. Isn’t it? Many people have confessed to me – you know, since I became a Christian I don’t swear anymore. And since I’ve became a Christian it’s amazing I talk different. Sometimes a family member will recognize that about another family member who has come to Jesus Christ – well, they talk so differently.
Well, that’s true because out of the abundance of the heart the mouth speaks. And if you’ve had a renewed heart then you’re going to have a renewed mouth.” -John McArthur (“Taming the Tongue” series, The Speech of the New Man, Part 1, Colossians 4:2)
In reference of Matthew 12:34
