Many Called!

“Many are called, but few are chosen” (Matthew 22:1-14) …may be freely paraphrased as follows. Many are called, but there will only be few who in following the call will prove worthy of, and act in accordance with, the fact that as the called of God they are His elect, predestined from all eternity for life with Him and for His service. There will only be few who in the words of 2 Pet. 1:10 are obedient to their calling and make sure, i.e., validate and confirm, their election. There will only be few who really are what they are as called, namely, elect or Christians. - K. Barth, Church Dogmatics IV, 3, p. 485.

Election!

Calvin 09 - Read The Institutes:

10. The elect before their call. There is no 'seed of election'

"The elect are gathered into Christ's flock by a call not immediately at birth, and not all at the same time, but according as it pleases God to dispense his grace to them. But before they are gathered unto that supreme Shepherd, they wander scattered in the wilderness common to all; and they do not differ at all from others except that they are protected by God's especial mercy from rushing headlong into the final ruin of death. If you look upon them, you will see Adam's offspring, who savor of the common corruption of the mass. The fact that they are not carried to utter and even desperate impiety is not due to any innate goodness of theirs but because the eye of God watches over their safety and his hand is outstretched to them!" - The Institutes of the Christian Religion, 3.24.10
