Oh, that's right. You have your own erroneous interpretation of gates and overpowering.
Let's review:
Matthew 16:18
And I tell you that you are Peter, and on this rock I will build my church, and the gates of Hades
[u] will not overpower it.
Ok. Who is Jesus "telling." Jesus is telling to Peter. What's he say? "On this rock I will build my church." Who's church is it? Jesus'. Who will build it? Jesus. Not you, not me. Not Paul, not Peter. Not evangelist. Jesus will build his church upon "this rock."
"And the gates of hell will not overpower it." I left the footnote link in above. Go see what the gates of Hades are. They are not physical or spiritual gates. They are metaphorical gates. More to the point, as the footnote points out, it is a metonymy. They represent the power of something, in this case hell. Well, hell (Hades) in the NT is equivalent to Sheol in the OT. Sheol is a prison for the unrighteous.
So if the glued butts in your church are unrighteous, then perhaps you have a point.
But, look again: "the gates of hell will not overpower it" What is "it"? Well, the church, obviously. Who or what is
doing the overpowering. Well, that's simple: the gates. Or the "power of death" as the footnote points out.
So it is the "power of death" that shall not overpower "the church."
No one in this verse is trying to overpower a gate. Nice try, but wrong.
You see, the locking up of Satan, and the silencing of the power of death, come much later (unless you are an amillennialist*) in time. So they are still trying to overpower the church and stop it.
But you stick with your butt glue.

* to be clear, even for the amillennialist all that comes later; they are simply wrong.
