God is the judge of everything, I agree with Noreasontohide. But about what Slashxii said, idk. I mean yeah certain things we are not supposed to speak, but the cursing, like those are just words. But if you say it to hurt someone or just for doin something bad, then that is what is not allowed/.
I love this song. I agree with what tdwp Freak says, but also a bit more. Like when it says keep singing now, means keep preaching. Spread his word, save as many as you can.
And Slashxii, may God help you in your preachings as he has done with me.
