Are you a believer?

Bible verses that are the standard definition of who is a Christian:

For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life. John 3:16 (NIV)

For all have sinned and fall short of the glory of God. Romans 3:23 (NIV)

For the wages of sin is death. Romans 6:23 (NIV)

For it is by grace you have been saved, through faith and this not from yourselves, it is the gift of God not by works, so that no one can boast. Ephesians 2:8-9 (NIV)

To summarize, the only way to be saved and go to heaven is by the grace of Jesus and by faith in God. These are the basic verses that every Christian who has accepted Christ knows. Now for the verses that clearly state that only Christians who believe the above will go to Heaven:
