Your answer to the above question will not have any bearing on how big Jesus really is, but it will reveal the condition of your own heart. If you respond to the light of Jesus with eagerness, and offer everything to him, Jesus will appear very large. If Jesus seems small to you, and you've shirked away from the light you have, you are agreeing with darkness. God isn't grading on a curve. The only way to enter heaven is by total acceptance of the light and being transformed into the likeness of Jesus. Have you cherished the gospel of Jesus Christ, or is it just an add-on to your already full life?
