Lots of good stuff here!
I understand God accepts us, we do not accept Him.
I understand the entire world," the field" has been bought by the work of Christ, the sacrifice of the perfect life of Christ. So the sins of the entire world are covered, past present, and future. But, that Grace doesn't benefit us unless we respond to the call of the Father " by Faith." And the application of how we receive Grace by Faith is the big problem!
How do you understand we receive Christ and His Grace by Faith?
I understand grace as the power of God that takes us into the will of God....the power to BE as Christ in the world.
By OUR faith we walk as good as we can according to our own level of maturity.
But by the faith OF Christ we walk as He walked. That is how we overcome sin. To do that we are translated to being IN Him by faith.
So there are 2 levels of faith. We are going from our faith to His faith. From faith to Faith. But we must be fully seeking God (surrendered) with the whole heart with OUR faith before we get the "upgrade" of faith to walk IN Christ. And it is God who accepts people into His Son and the eternal life. Not us who decides.
Holiness is built on righteousness. An upper room so to speak.
