According to the Bible, Enoch and Elijah are the only two people that God took to heaven without them dying. Genesis 5:24 tells us, "So Enoch walked with God, and he disappeared, because God took him." 2 Kings 2:11 tells us: "... behold, a chariot of fire with horses of fire separated the two, and Elijah went up into heaven in a whirlwind." Enoch is described as a man who "walked ... with God ... three hundred years." (Genesis 5:22) Elijah was perhaps the most powerful of the prophets of God in the Old Testament. There are also prophecies of the return of Elijah (Malachi 4: 5-6).
Why did God lead Enoch and Elijah?
The Bible does not give us the answer specifically. Some speculate that they were brought in preparation for a role in recent times, possibly as the two witnesses of Revelation chapter 11: 3-12. This is possible, but not explicitly taught in the Bible. It may be that God wished to save Enoch and Elijah from experiencing death because of their great fidelity in serving and obeying Him. In any case, God has His purpose, and while we do not always understand the plans and purposes of God, we know that "His way is perfect" (Psalm 18:30).
