Whether you're a doubter or another agitator, just look at what the Bible says:
1- Jesus started one true Christian religion. After the Christian arrangement had been established for some time, the Apostle Paul under inspiration further showed at Ephesians 4:4, 5 that there must be just one body, or group, of true worshipers of God. Plus, Jesus taught us at Matthew 7:13, 14 that only a few people are on the narrow road to life.
2- The Bible foretold at Matthew 7:15, 21-23 that after the death of the apostles, wrong teachings and unchristian practices would slowly come into the Christian congregation. And Acts 20:29, 30 show that men would draw away believers to follow them instead of Christ. That is why we see so many different religions that claim to be Christian, but that doesn't mean that they are all acceptable ways to God.
3- The most outstanding mark of true Christians according to John 13:34, 35 is that they have real love among themselves. They are not taught to think that they are better than people of other races or skin color. They aren't taught to hate people from other countries. So they do not share in wars.
4- Another mark of true religion is that its members have a deep respect for the Bible. They accept it as the Word of God and believe what it says. They treat God's Word as being more important than human ideas or customs, as Jesus stressed that importance at Matthew 15:1-3, 7-9. They try to live by the Bible in their everyday life. So they do not preach one thing and then practice another.
5- According to Matthew 6:9 the true religion must also honor God's name. Jesus made God's name, Jehovah, known to others. True Christians must do the same.
6- True Christians must preach about God's Kingdom. Jesus did so. He always talked about the Kingdom. At Matthew 24:14 and 28:19 he commanded his disciples to preach this same message in all the earth. That Kingdom is the only thing that will bring true peace and security to this earth
And finally,
7- Jesus' disciples must be no part of this wicked world, as stated at John 17:16. They do not get involved in the world's political affairs and social controversies. They avoid the harmful conduct, practices, and attitudes that are common in the world.
