There are VERY few reasons to put somebody on ignore in my opinion. This is one of them.
some the letters in my new name have sensitive feelings.
Does it say that somewhere in the Book of Revelation?
only if you're referring to the following:
Revelation 2:17
He who has an ear, let him hear what the Spirit says to the churches. To him who overcomes, I will give some of the hidden manna. I will also give him a white stone with a new name written on it, known only to him who receives it.
Revelation 3:12
Him who overcomes I will make a pillar in the temple of my God. Never again will he leave it. I will write on him the name of my God and the name of the city of my God, the new Jerusalem, which is coming down out of heaven from my God; and I will also write on him my new name.
Actually, I was talking about the letters' sensitivity.
