Therefore, if anyone is in Christ, he is a new creation; old things have passed away; behold, all things have become new. - 2 Cor 5:17
For you are all sons of God through faith in Christ Jesus. 27 For as many of you as were baptized into Christ have put on Christ. 28 There is neither Jew nor Greek, there is neither slave nor free, there is neither male nor female; for you are all one in Christ Jesus. - Gal 3:26-28
I beseech you therefore, brethren, by the mercies of God, that you present your bodies a living sacrifice, holy, acceptable to God, which is your reasonable service. 2 And do not be conformed to this world, but be transformed by the renewing of your mind, that you may prove what is that good and acceptable and perfect will of God. - Romans 12:1-2
The above passages paint vivid pictures of the new man. The moment you accepted Jesus as your Lord and Savior, you were born again into the family of God. You have a brand new spirit. The new you is neither Jew nor Greek, neither slave nor free, and neither male nor female. However, because you are triune being, you still have two-thirds of you that isn't brand new. For emphasis: you are a spirit, you have a soul and you live in an earthly suit, your body (1The 5:23).
