Do only Christians go to heaven?
The only Scripture that comes close to saying, "go to heaven," is from the deepest heartfelt thought of SATAN THE DEVIL:
"How thou art fallen FROM HEAVEN, O LUCIFER... For THOU HAST SAID IN THINE HEART, 'I WILL ASCEND INTO HEAVEN...' [I WILL GO TO HEAVEN]" (Isa.14:12-13).
Nowhere in the Bible does God permit or promise man... ANY MAN... that he will go to heaven [that is, the "3rd heaven" where His throne is. The first two heavens of which the Bible speaks; man has gone and often repeatedly: the first one within the earth's breathable atmosphere where birds fly and clouds form, man goes to daily. Visit any airport around the world and watch him go. The second heaven, where the stars and planets reside in vacuous "outer space," man has gone also... but with great deliberation and difficulty].
It's SATAN who desires to go to the third heaven of God's throne -- because he wants to BE GOD:
"...'I WILL EXALT MY THRONE ABOVE THE STARS [angels - see Rev.1:20] OF GOD...'" (Isa.14:13).
But since man began to worship and obey "that old Serpent, called the Devil, and Satan" [Rev.12:9] from the beginning... it naturally followed that all of the succeeding "false religions" in the world that he foisted upon deceived mankind would include GOING TO HEAVEN.
Certainly, Muslims believe that only Muslims "go to heaven"... while all other people go to "the other place" [or whatever places their ministers, priests, imams, or whatever relegate anyone who doesn't believe their way].
As for those who profess the so-called "Christian" religion... the Bible reveals that they shall inherit whatever it was that God promised to ABRAHAM!
...IF YE BE CHRIST'S, then YE ARE ABRAHAM'S SEED, and HEIRS ACCORDING TO THE PROMISE." (Gal.3:29)
So the question is: WHAT DID GOD PROMISE ABRAHAM? HEAVEN?
NO! God promised Abraham "LAND!" Not heaven! The Promised LAND! God promised Abraham THE EARTH!
"For THE PROMISE, THAT HE SHOULD BE THE HEIR OF THE WORLD, was not to Abraham, OR TO HIS SEED, through the Law, but THROUGH THE RIGHTEOUSNESS OF FAITH." (Rom.4:13)
The Bible promises NO ONE heaven... regardless of whatever false religion they happen to believe. It promises the "Righteous Faithful" of God THE EARTH:
God... "...hast made US unto our God Kings and Priests: and WE SHALL REIGN ON THE EARTH." (Rev.5:10)
There are Christians who believe only Christians go the heaven and there are Christians who believe all good people go the heaven. Those views are so divergent because no one really knows. And they do not know because there is no evidence that heaven even exists.
