The Power of Grace in God's Effectual Calling

The power of God's grace is communicated particularly in the word calling.  In the Pauline literature the word should not be defined as an "invitation' that can be accepted or refused.  Calling is performative, in which the call accomplishes what is demanded.  This is apparent in reflecting on a number of texts.  For instance, in Romans 8:30 Paul says that "those whom he called, these he justified."  In this verse all of those who are called are also justified.  No exception intervenes so that only some of those who are called are justified.  Every single person who is called is also justified.  Thomas The Apostle of God's Glory in Christ, p. 240-241.
