The Bible tells us who Jesus is to Christians, in the New Testament:
“The Son is the image of the invisible God, the firstborn over all creation. For in him all things were created: things in heaven and on earth, visible and invisible, whether thrones or powers or rulers or authorities; all things have been created through him and for him. He is before all things, and in him all things hold together.”
“And he is the head of the body, the church; he is the beginning and the firstborn from among the dead, so that in everything he might have the supremacy… “
“Once you were alienated from God and were enemies in your minds because of your evil behavior. But now he has reconciled you by Christ’s physical body through death to present you holy in his sight, without blemish and free from accusation…“ ~ (Col 1:15-23, New Testament Bible)
