You come before the judgment seat of God full of rebellion and mistakes. Because of his justice he cannot dismiss your sin, but because of his love he cannot dismiss you. So, in an act which stunned the heavens, he punished himself on the cross for your sins. God’s justice and love are equally honored. And you, God’s creation, are forgiven.
The difference between people who succeed and people who fail, I think in many cases it’s not fear. Everyone experiences fear. The difference is what do you do with your fear. Do you work to overcome it or do you let it defeat you? And I think that is actually what distinguishes very successful people from others.
