I have no axe to grind here; I'm just looking for an explanation. Luk 1:13 But the angel said to him, "Do not be afraid, Zechariah, for your prayer has been heard, and your wife Elizabeth will bear you a son, and you shall call his name John. Luk 1:14 And you will have joy and gladness, and many will rejoice at his birth, Luk 1:15 for he will be great before the Lord. And he must not drink wine or strong drink, and he will be filled with the Holy Spirit, even from his mother's womb. (ESV) I would like to see non-Calvinists explain this event. How could John be filled with Holy Spirit from birth if salvation involves any kind of choice? Is this case the exception to the rule? Any and all explanations are welcome.
