What we find here,
is that the worshipers are very few. How do we know that? Because John was told to count them. You can’t count the stars; there are too many of them. You can’t count the sand on the seashore; there are too many of them. You can’t count the water droplets in the ocean; there are too many of them. We can’t even count all the people in the world today, using our sophisticated, scientific equipment. We can’t even count all the people in L.A. We can come to a close approximate, but we can’t be sure we have counted every single one. Therefore, when John was told to count, it was because he was able to.
"Enter through the narrow gate. For wide is the gate and broad is the road that leads to destruction, and many enter through it. But small is the gate and narrow the road that leads to life, and only a few find it." Matthew 7:13, 14
The Gentiles are symbolic of those who do not worship the true God. They have set up their own institutions of worship. They have built big cathedrals and churches; however, God is not among them since they do not obey His Ten Commandments and the 7th day Saturday Sabbath.
