Luke 1:67โ€“80 (CSB)
Then his father Zechariah was filled with the Holy Spirit and prophesied:
Blessed is the Lord, the God of Israel,
because he has visited
and provided redemption for his people.
He has raised up a horn of salvation for us
in the house of his servant David,
just as he spoke by the mouth
of his holy prophets in ancient times;
salvation from our enemies
and from the hand of those who hate us.
He has dealt mercifully with our ancestors
and remembered his holy covenantโ€”
the oath that he swore to our father Abraham.
He has given us the privilege,
since we have been rescued
from the hand of our enemies,
to serve him without fear
in holiness and righteousness
in his presence all our days.
And you, child, will be called
a prophet of the Most High,
for you will go before the Lord
to prepare his ways,
to give his people knowledge of salvation
through the forgiveness of their sins.
Because of our Godโ€™s merciful compassion,
the dawn from on high will visit us
to shine on those who live in darkness
and the shadow of death,
to guide our feet into the way of peace.

The child grew up and became strong in spirit, and he was in the wilderness until the day of his public appearance to Israel.

Giving Zechariah's prophesy, what did the Old Testament reveal about God and what He promised He will do for his people?

What was Zechariah's son called to do?

What are we called to do if we believe and trust in God?
