2 Corinthians 5:14-17

14 Either way, Christ’s love controls us. Since we believe that Christ died for all, we also believe that we have all died to our old life.
15 He died for everyone so that those who receive his new life will no longer live for themselves. Instead, they will live for Christ, who died and was raised for them.
16 So we have stopped evaluating others from a human point of view. At one time we thought of Christ merely from a human point of view. How differently we know him now!
17 This means that anyone who belongs to Christ has become a new person. The old life is gone; a new life has begun!
