God's basis must be our basis for acceptance. There is none other. We are "accepted in the Beloved." Our Father is fully satisfied with His Beloved Son on our behalf, and there is no reason for us not to be. Our satisfaction can only spring from and rest in His satisfaction. It is from God to us, not from us to God. J. N. Darby was very clear on this:

"When the Holy Spirit reasons with man, He does not reason from what man is for God, but from what God is to man. Souls reason from what they are in themselves as to whether God can accept them. He cannot accept you thus; you are looking for righteousness in yourself as a ground of acceptance with Him. You cannot get peace whilst reasoning in that way.

"The Holy Spirit always reasons down from what God is, and this produces a total change in my soul. It is not that I abhor my sins; indeed I may have been walking very well; but it is 'I abhor myself.' This is how the Holy Spirit reasons; He shows us what we are, and that is one reason why He often seems to be very hard and does not give peace to the soul, as we are not relieved until we experientially, from our hearts, acknowledge what we are.

"Until the soul comes to that point He does not give it peace—He could not it would be healing the wound slightly. The soul has to go on until it finds there is nothing to rest on but the abstract goodness of God; and then, 'If God be for us, who can be against us?' (Rom. 8:31b)."
