The first was separation from his kindred and country at the Divine command. The call of Abraham is typical of that call of the Holy Spirit, which sooner or later comes to every sinner, to turn away from all known sin as a preparation for saving faith in Christ.
The second point of transition in Abraham's life was his justification by faith. He believed in Jehovah; and He counted it to him for righteousness. St. Paul cites this as a conspicuous instance of justification by faith under the old covenant. Abraham had exercised faith in obeying the call to separation; but it was what theologians style prevenient rather than saving faith.
