As it so often happens in researching one subject to veer off into something else, often multiple things. I found the following Scripture to be incredibly descriptive in regard to His called since the establishment of the early (1st century) church, although the first eight verses are from the OT and speak directly to physical Israel we can see that in "Acts" (Luke?) used the same terminology with the church(es) of his time and I am sure to the future church(es) as well.
Do these verses speak anything to you?
Exo 32:9 And the LORD said unto Moses, I have seen this people, and, behold, it is a stiffnecked people:
Exo 33:3 Unto a land flowing with milk and honey: for I will not go up in the midst of thee; for thou art a stiffnecked people: lest I consume thee in the way.
Exo 33:5 For the LORD had said unto Moses, Say unto the children of Israel, Ye are a stiffnecked people: I will come up into the midst of thee in a moment, and consume thee: therefore now put off thy ornaments from thee, that I may know what to do unto thee.
Exo 34:9 And he said, If now I have found grace in thy sight, O Lord, let my Lord, I pray thee, go among us; for it is a stiffnecked people; and pardon our iniquity and our sin, and take us for thine inheritance.
Deu 9:6 Understand therefore, that the LORD thy God giveth thee not this good land to possess it for thy righteousness; for thou art a stiffnecked people.
Deu 9:13 Furthermore the LORD spoke unto me, saying, I have seen this people, and, behold, it is a stiffnecked people:
Deu 10:16 Circumcise therefore the foreskin of your heart, and be no more stiffnecked.
2Ch 30:8 Now be ye not stiffnecked, as your fathers were, but yield yourselves unto the LORD, and enter into his sanctuary, which he hath sanctified forever: and serve the LORD your God, that the fierceness of his wrath may turn away from you.
Act 7:51 Ye stiffnecked and uncircumcised in heart and ears, ye do always resist the Holy Ghost: as your fathers did, so do ye.
