We must remember that God is "long-suffering, not willing that any should perish." He always sends His signs, His wonders. And then when He gets ready to do anything, He separates the believer from the unbeliever.
Don't sin wilfully. Don't disobey wilfully. If there is something in you, that say, "Well, now, I don't see where I need the Holy Ghost. I might not need It. I believe, when I believed, I got It."
Paul said, to the people that asked that question, he said, "Have you received the Holy Ghost since you have believed?"
The Holy Ghost is the Token. A man believes God, that is true enough. But the Holy Ghost is a gift of God, it's something different than your faith. Your faith applies it, that's exactly right, but the Holy Ghost is the witness. We'll see, just in a few minutes, how It works, and what takes place, where we can be sure, where we know where we're right, or not. It warns us that the time is at hand.
We should love one another. During this time, the church and the believer should be unseparable. Believers, believers should separate themselves from all the things of the world.
