To truly believe in Jesus, we must believe the Jesus described in the Bible. The Jesus of the Bible is God. He is the Son of God Who came in the flesh, to die in the flesh, so that we may live forever with Him and see Him with my own eyes!
Knowing that the word of God has no errors, there must be a proper way to understand these differing accounts.
If we have the idea that we are good enough for heaven, we have far to view a high of ourselves.
