Born Again is NOT a religion. Its a relationship. A deep, personal relationship with God. The meaning of the "born again" in John 3:3 is-- to be re-born as a new identity in Christ after encountering the truth and knowing the his real purpose.
Born again is not a religion. Religion separates people. Some religion doesnt welcome other religions while born again people are always delighted to welcome others regardless of who they are, what they were, what religion, poor, rich, or bsag kinsa pa na. Jesus didnt have a religion. As well as his disciples. He did not teach and preach any religion. Salvation is only by grace through faith in Jesus Christ. ☺️
