“So then, if anyone is in Christ, he is a new creation; what is old has passed away—look, what is new has come!”
2 Corinthians 5.17
Christians have a new reality in Christ. Even their perspectives about others change, v. 16. Their hopes, their dreams, their purpose in life are all new. They now work for reconciliation, vv. 18-21.
We get into Christ by baptism, Rom 6.4. Not by the passage of time, but by conversion, do we experience something new. With man, there’s never anything new, Eccl 1.9. With God, every day is a new day.
