Re: Two Covenants, Not one

Isaac was Israel's father, and Abraham's son. When we become part of spiritual Israel, there is no longer Jews or Gentiles. Galatians 3:28

The New Covenant is in Hebrews 8:8-12.

Romans 7:14 For we know that the law is spirtual: but I am carnal, sold under sin.

Galatians 5:16 This I say then, Walk in the Spirit, and ye shall not fulfil the lust of the flesh.

Walking is your physical actions.
