Yes, John 10:2 confirms there is a door that remains the door! The idea is that there is a door, a proper way to gain entry. Not everyone who stands among the sheep comes that way; some climb up some other way. The religious leaders earned their place among God’s people – the sheep spoken of here – through personal and political connections, formal education, ambition, manipulation, and corruption. At this point, Jesus is not speaking about heaven. His analogy has a well-defined purpose, not directly related to salvation or attaining eternal life. As Jesus will say, later on, those who are “His,” as it pertains to everlasting life, cannot be “stolen” in the way a robber in this particular analogy would do. Instead, this symbol is about how and why certain people respond to the gospel’s message and others do not. Jesus is the door!!!
