The Bible says that Jesus is the path to eternal life. John 6:67-69. In Matthew 28: 18,19 Jesus said, "All authority in heaven and on earth has been given to me. Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit' Matthew 28: 18-19
Ponder upon the words of Jesus especially if you are a Jehovah's Witness. Notice that ALL authority is given to Jesus and when Christians get baptized they have a direct relationship with Jesus through the Holy Spirit. They don't worship God through a middle man.
Critics say God's people belong to God, not an organization or religion. That's why true Christian religions do not judge God's people. It is not appropriate for church leaders to judge Christians on behalf of God. Judicial committees, disfellowshipping, and keeping God's organization clean is God's business. All people on this planet are 'his' people, not just Jehovah's Witnesses.
Religious leaders should be examples of God's unconditional love, not judges for God's organization. Religions should teach good and honorable doctrines, but individuals should be free to listen to their own conscience and worship God directly.
The Apostle Paul disagreed with Jesus. Jesus told us not to judge. Luke 6:27-41; Get The Facts About The Apostle Paul
Since law of the Christ is freedom, Christians should be free. In the early days, Jehovah's Witnesses said that religions are a snare and a racket. Modern day Jehovah's Witness leaders have forgotten that religions should not trap God's people. God's people are meant to be free to worship God according to their conscience.
God's people can attend any church because all people belong to God. No one can disfellowship you from God's organization. All they can do is disfellowship you from their church. No religion is perfect enough to take on the title of God's organization.
