The Bible has some outstanding statements that simply will blow your mind. That is, if we only read them correctly. For instance, when the Bible mentions eternal, or eternity, we often interchange the meaning with forever, or long lasting. Forever is a long, long, long, long time (pardon the stretch on Grammar here). But it is still time-based.
However, eternal means never had a beginning, so certainly, there will never ever be an end. It is from everlasting to everlasting, and beyond. That is mind-blowing.
Paul in 1 Timothy 1: 17 says we have a King eternal, immortal, and invisible. So read it again.
There are certain attributes of God that have a beginning. For instance, Jesus cannot be an eternal son. Simply because all sons must have a beginning. They must come from a father. Jesus, was begotten of the Heavenly Father.
But God says He’s an Eternal King. Meaning, He always was a King. And He will always be King. Even when other kings come in the future to reign with Him (Revelation 5:10) He will remain KINGS OF KINGS (Revelation 19:16).
He was always The King. No wonder all kingdoms must fall. All kingdoms must have an end, so that He can establish His Kingdom, that will not have an end.
It makes everlasting sense to me.
