Religion is not the major thing that saves us in our life. Salvation is mostly all about how we believe in God worship him and trust him in our life. A person may belong to a particular religious group, attend church regularly, or participate in religious activities, but these things alone do not guarantee salvation. What matters is a genuine relationship with God that produces faith, repentance, obedience, love, and a transformed life.
Religion can still be useful because it can help people learn about God, worship Him, fellowship with other believers, and grow spiritually. However, religious membership should not replace genuine faith and obedience to God.
