If God is on your side, why is life littered by unwanted challenges and broken dreams? Luke is introducing us to Zechariah and his wife Elizabeth - a godly, devout, faithful couple who obeyed the Jewish rules. They were both descended from Aaron so Zechariah was a priest who served in the temple, and any male children would, automatically, have become priests. But there was not even one child. This was also a personal spiritual problem because, in the Old Testament, fertility was a mark of God's blessing. No child, and in some way, God must be displeased.
