I'm sure you know psalms 121 for example
My help comes from the Lord the maker of heaven and earth
But heaven is a christian creation according to you right?
Or how about Elijah going up to heaven
Universe, Universal Laws, Universal Truths > Religions.
The Universe contains religions, not the other way around. One may believe in the heavens (look to the sky) but it is not necessary to subscribe to a religious belief. It will only keep you away from knowledge in other religions. Think of a Religion as a Class/Course, and Life/The Universe as the School. We use "religions" or schools of thoughts, philosophies, etc to understand the human experience we are going through.
Let me clarify, I do believe in "heaven" or something otherwordly but not in Christianity.
I don't like the VIP membership certain religions got going on. They don't teach the half of it.
Elijah going to Heaven in a chariot of Fire.
Would you think it possible that through God's intervention he was able to raise his vibration and leave our dimension in a burst of light? The angel Metatron was said to once be human and became an angel who gave us Metatron's Cube. A 4th dimensional blueprint deciphered from sacred geometery which gives us insight into the mechanics of light and vibration.
