Does Jesus acknowledge that he was the offspring of Abraham?
John 8:58 says,“Jesus said to them, Truly, truly, I say to you, Before Abraham was, I am.” How can we explain this?
I suppose the insurmountable problem you face is discerning when it is Jesus as the Son of God or Jesus as the son of Mary doing the speaking.
Remember this and nail it down solid....
No man, no, nor the blood of bulls can represent the Lord God.
Only a man and not the blood of bulls can represent mankind.
In Jesus we have the coming together of the two 'litigants' As the Son of God, Jesus is the perfect representative of God.... The only possible representative of the Lord God.
Speaking of Jesus,
Col 2:8. See to it that no one takes you captive by philosophy and empty deceit, according to human tradition, according to the elemental spirits of the world, and not according to Christ.
Col 2:9. For in him the whole fullness of deity dwells bodily,
Col 2:10. and you have been filled in him, who is the head of all rule and authority.
And speaking of Jesus as the son of Mary, the only one who can stand as representative of mankind.
1Ti 2:5. For there is one God, and there is one mediator between God and men, the man Christ Jesus,
1Ti 2:6. who gave himself as a ransom for all, which is the testimony given at the proper time.
Now i want to stress and impress this upon you:
Eph 2:8. For by grace you have been saved through faith. And this is not your own doing; it is the gift of God,
This faith being spoken of is faith in Jesus as the Christ of God, but note well that we can not have faith in just a part of Jesus.
If we have faith in Jesus, it must embrace the whole Jesus. Jesus the Son of God, Jesus the son of Mary (man).
We can not pick and choose what appeals to us and reject the rest. The whole of Jesus is what the Lord has put on offer for our salvation, and He is the one in whom our faith must reside.
