Isaiah 43:7

Even everyone that is called by my name,.... That is called by the name of God, a son or daughter of his; or by the name of Christ, a Christian; whoever belongs to the Lord, whom he calls by his name; and who, being called by his grace, call upon his name, make a profession of his name, and serve and worship him:

for I have created him for my glory, I have formed him, yea, I have made him; all which is expressive of the power and grace of God, in the regeneration and conversion of his people; which is a creation, a formation, a making them for himself, for the glory of his grace, and to show forth his praise; and therefore he will gather them in, and bring them into a body together, into a church state, that this end may be answered.
