We are in Christ, thru the Body of Christ. When God sees us, he sees us "in Christ".
We are saved thru being in that same body (Ephesians 1:7).
If you prefer to be saved under the New Covenant, you don't have forgiveness of your sins NOW, you will only receive that in the future, together with saved Israel (Hebrews 8:12)
You are quoting from the new covenant!
Hebrews 8:10 This is the covenant I will establish with the people of Israel
after that time, declares the Lord.
I will put my laws in their minds
and write them on their hearts.
I will be their God,
and they will be my people.
11 No longer will they teach their neighbor,
or say to one another, ‘Know the Lord,’
because they will all know me,
from the least of them to the greatest.
12 For I will forgive their wickedness
and will remember their sins no more.”
According to you, this promise does not apply to you.
12 For I will forgive their wickedness
and will remember their sins no more.”
because
Hebrew 8:10 This is the covenant I will establish with the people of Israel
after that time, declares the Lord.
Which is not the case and the point we have been trying to make. If we are of Christ we are part of God's Israel and heir to the promises and inheritances.
