In the Garden, God created man, both Adam and Eve. They were created immortal, but because of their disobedience they fell from God’s presence and the divine relationship was broken. From these two sprang all human life. There was only one true race of people. There was not a black race or a white race or a brown race or a yellow race. All were similar and all were equal. All were equally precious but all were equally lost.
At the resurrection of Christ, God created a new race of people, called Christians. These are humans that have been restored from the fall of Adam and Eve. They have a new heart and a new spirit. For them the divine relationship has been restored. Their relationship is no longer with a fallen world but with a living God, through a risen Savior. They are called the New Creation.
Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new. 2 Corinthians 5:17
Now, there are two races of people on the earth, one fallen, and the other restored. However, there is conflict between them for they serve two different masters and have two different hearts. Fallen man will fall at the end of the age, and restored man will rise at the end and live with God forever. Both are immortal. Read – Salvation
And have put on the new man, which is renewed in knowledge after the image of Him that created him; Colossians 3:10
