Romans 3:22 This righteousness is given through faith in Jesus Christ to all who believe. There is no difference between Jew and Gentile
After Christ had gone back to be with God in Heaven, people had to learn a new way of faith... not by seeing the constant stream of miracles anymore, but because they had already happened.
You may think this is easier now because we have the proof... Well, I don’t see large queues of people trying to get into church, so I guess it’s not!
No matter what we call ourselves, we all answer to Christ because of what He has done for us, personally!
We need to cling to the faith He will return!
