A Change of Heart

The be a Christian is to live one's life not merely in obedience to God, nor merely in dependence on God, nor even merely for the sake of God; it is to stand in conscious, reciprocal fellowship with God, to be identified with Him in though and purpose and work, to receive from Him and give back to Him in the ceaseless interplay of spiritual forces...According to this the covenant means that God gives himself to man and man gives himself to God for that full measure of mutual acquaintance and enjoyment of which each side to the relation is capable.

William Edgar quoting Geerhardus Vos in Without Apology: Why I Am A Presuppositionalist.
