This is one of the most foundational questions when we deal with life and the certainty of death. The Bible says that when we die, we will either go to Heaven or hell. Passages like Daniel 12:2,3 Matthew 25:46, Revelation 20:14,15 show us that upon our death there are only 2 destinations, Heaven or hell.
Whether or not you end up in Heaven or hell will depend on whether or not you have put your trust in Jesus Christ alone as your savior (John 3:16). The decision to put your trust in Jesus Christ as your Savior guarantees eternal life in Heaven. The decision to reject Jesus Christ as your savior results in an eternity in hell, separated from God.
There are only 2 destinations after death, Heaven or hell. Where we go depends solely on our trust or rejection of Christ as savior.
