We find out in this there's a mixed multitude. Many times people go out saying, "Yes, I am. I'll do this." And we find out that those people were carnal. Just as soon as the first little strain come, they desired to go back into Egypt. They wanted the garlic pots; they wanted the fish out of the river; they wanted the leek and the garlic; they wanted the things that they had down in Egypt.
That's a beautiful and a perfect type of the carnal church member today. He loves the things of the world because he's not of God. The Bible said, "If you love the world or the things of the world, the love of God's not even in you." And Christ is right in all of His statements. And that's true.

no matter how much you've tried to pretend, when it comes to a strain, a man will show his best and worst points under strain. Take a Christian sometime and put him under a strain and watch how he acts, and you can tell what he's made out of.

Everybody can go good; everybody can praise the Lord while the Holy Spirit's a falling in a congregation of people. But let trouble arise and watch what takes place. Watch what happens then. There you'll follow them around? Are you one of the mixed multitude? Are you the person who can't (as the street expression say), can't take it? That's it. You can't stand up to it. Brother, if you've got that way, backslidings, and up-and-downs, and ins-and-outs, why don't you come to Calvary and die out to yourself and be borned again of the Spirit of God? Amen.
Shame on you.

You who profess Christianity, you who live in your churches. We have no members here; you just come here; you belong to all different churches. But you people who profess to be Christians, and then live something else life, that you're not here and an indebtiment to the society of the Lord Jesus Christ. Amen. You who profess to be Christians and are ashamed to take Him at His Word or testify to His power and glory when He comes, you're indebtiment to the Name of the Lord Jesus Christ. Amen. That's true. That's right. Flee to the Word, sink or drown ground, stand on His Word.
