That passage is about not being a hypocrite.
We judge all the time. It's called logical thinking, having opinions and making decisions based on Truth
Everyone is eternal in the sense that we are all going somewhere when we die.
But some of us will go to Hell, and some of us to Heaven.
Hell is referred to as Death, Heaven is Life.
I am eternal because I have eternal life. Not by my own power, but by the mercy of God through the blood of Christ, which is the Gift of God to all men who believe on His name, be humble and repent from their own pride.
I'm not afraid OF you.
I am afraid FOR you. Two very different things.
Pride is the sin of Satan, and the sin of Sodom. It is the principle cause of self-destruction.
You believe that you don't need the mercy of God to see the Afterlife, but that is not what the Bible says. You must be humble and submit yourself to Him that created you and gave you life.
My words are not for my own benefit. My church doesn't care how much money they get in their offering plate, unlike the Catholics who deck their buildings in gold and idols of blasphemy, and scare/coerce people into submitting to them, rather than submitting to God.
I speak all these things for your admonition and your benefit.
The Bible is very clear about Heaven and Hell.
Destiny is a matter of Choice. God is giving you the keys to Heaven, but you have to be humble enough to receive that gift and trust His Word
