The denominations set up by men which people think that membership in or adherence to makes them Christian or somehow saved, is meaningless. Those denominations, ALL denominations, are organizations set up by men. They're RELIGIONS. They CANNOT save.
Christianity is not about religion, religious duties, religious anything. It's about a personal relationship with Christ, having been forgiven and adopted into His family as joint heirs with Christ by grace through faith.
Churches and denominations are about rules and regs and controlling the membership. Being in Christ is about being free. Whoever the Son has set free is free indeed.
John 8:31-36 31So Jesus said to the Jews who had believed in him, "If you abide in my word, you are truly my disciples, 32and you will know the truth, and the truth will set you free." 33They answered him, "We are offspring of Abraham and have never been enslaved to anyone. How is it that you say, 'You will become free'?"
34Jesus answered them, "Truly, truly, I say to you, everyone who commits sin is a slave to sin. 35 The slave does not remain in the house forever; the son remains forever. 36So if the Son sets you free, you will be free indeed.
Are you already forgiven for sins you haven’t repented?
