God is the Creator of two creations. In the beginning He created the heavens and the earth first, and man last. In the new creation the order is reversed; God is now creating men anew in Christ Jesus, and hereafter will fashion a new heavens and a new earth. (2 Cor. 5:17; Rev. 21:1.)
To lay hold by faith, the truth of the new creation is an immense blessing. "If any man be in Christ, he is a new creature [or, there is a new creation]: old things are passed away; behold, all things are become new." 2 Cor. 5:17.
Adam, created in innocence, was tempted and sinned. The Christian, created anew in Christ, has a new nature which cannot sin. The old, Adam nature in the believer is not one whit improved, but everyone who is in Christ is a new creation. Thus God sees him forever.
Those who are in Christ are also spoken of as created in Christ Jesus unto good works.
“God... hath quickened us together with Christ, (by grace ye are saved;) and hath raised us up together, and made us sit together in heavenly places in Christ Jesus: that in the ages to come He might show the exceeding riches of His grace in His kindness toward us through Christ Jesus. For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: not of works, lest any man should boast. For we are His workmanship, created in Christ Jesus unto good works." Eph. 2:4-10.
“And that ye [having] put on the new man, which after God is created in righteousness and true holiness." Eph. 4:24. The new creation is God's own perfect handiwork. And "whatsoever God doeth, it shall be forever." Eccl. 3:14. Are you a new creation in Christ? Young Christian
