2 Corinthians 5 is about the concept of reconciliation. Paul talks about how as believers, we no longer see people based on their physical appearance, but rather as new creations in Christ. He goes on to explain that God reconciled us to Himself through Christ, and has given us the task of sharing this message with others so that they too might be reconciled to God. Paul also touches on the idea of judgment, noting that we will all one day stand before Christ and give an account of our deeds, which he uses as a motivation to follow Christ and live for Him.
