2 Corinthians 5:17 - Joseph Benson’s Commentary on the Old and New Testaments

Therefore Since all Christ's true disciples do thus live to him, and not to themselves, and only know him in a spiritual manner; if any man be in Christ By living faith and the indwelling of his Spirit; if any man have an interest in and union with him; he is a new creature Καινη κτισις, there is a new creation, in the soul of that man. His understanding is enlightened, his judgment corrected, and he has new ideas and conceptions of things. His conscience is informed, awakened, and purged from guilt by the blood of Jesus, Hebrews 9:14. His will is subjected to the will of God, his affections drawn from earth to heaven, and his dispositions, words, and actions, his cares, labours, and pursuits, are all changed. Old things are passed away All old principles and practices; behold The present, visible, undeniable change! all things are become new He has new life, namely, a spiritual and divine life; new spiritual senses, new faculties, new desires and designs, hopes and fears, joys and sorrows, passions and appetites. His whole tenor of action and conversation is new, and he lives as it were in a new world. God, Christ, the Holy Spirit, angels, men, sinners, saints, and the whole creation heaven, earth, and all therein, appear in a new light, and stand related to him in a new manner, since he was created anew in Christ Jesus.
