That might be the one thing that keeps you out of the Kingdom

The Uncertain Sound

Now. But if there's a question… Men come, said, “Do you think it's wrong to smoke?”
“What are you asking about it for?” If it's a question in your mind, leave it alone. For anything you don't do by faith is sin. That's right. Got to be by faith. So how can you smoke and have faith? See, it's right in your own conscience shows you that you're wrong. So if it's uncertain, you better leave it alone, ’cause that might be the one thing that keeps you out of the Kingdom of God.
“Oh,” you say, “Brother Branham, one little thing like that?”
One little thing like that will do it, just disobeying one commandment of God.

And grieve not the holy Spirit of God, whereby ye are sealed unto the day of redemption.
