Second Sunday of Advent – December 7, 2025

Matthew 3:1-12

Imagine this: An envelope arrives in your mailbox.

  • It appears like any other holiday card.
  • It is a plain white envelope…not green or red.
  • When opened…the card does not portray the holy family…a starlit night or shepherds or wisemen.
  • Instead…there is a burly figure with a grim look on his face.
  • And the inside of the card reads:
  • Happy Advent…You Brood of Vipers! signed…John the Baptist.

John arrives every year on schedule…doesn’t he?

  • On the second Sunday of Advent…this strange figure steps right out of the desert and right into to our festive preparations.
  • John dresses like an ancient prophet in camel’s hair.
  • He works in the wilderness…not in a civilized city.
  • He preaches with sternness…
  • And he calls everyone who can hear him to repent.
  • The Lord be with you.

Repent is a verb that makes us uncomfortable.

  • And that is because we conclude that Christian faith is primarily about behavior…
  • Defined by what we should or should not do.
  • As the old adage puts it: Don’t drink…dance or chew…or date the girls that do.
  • So…preaching becomes a harangue against bad behavior…however described or imagined.

In times of moral confusion…some have found it helpful to make a list of do’s and don’ts.

  • Wrongdoings go in the don’t
  • Right-doings go in the do
  • The instruction is clear: move from the bad column to the good column.
  • Straighten up and fly right…change your ways.
  • Behave better than before.
  • In that kind of religious system…we really do not need a living God…we just need a list.

A funny thing happens when we live only by a list of behaviors.

  • We start grading the items on our list.
  • Some sins are perceived as worse than others.
  • For some reason…smugness and self-righteousness never make the list.
  • Neither do greed or abuse of power.
  • So…there is no real possibility of repentance…and so…we just return to the list.

John the Baptist did not maintain a list of sins.

  • Instead…he invited people into the presence of God.
  • John never barked at people to change.
  • Instead…he announced God was knocking at the door.
  • The kingdom of heaven has come near…he said.
  • And this is the proper context for forgiveness.
  • John the Baptist does not wag his finger at bad behavior…
  • Instead…he points to God!

His singular sermon is that God is coming toward us.

  • And his message brings everybody to the desert.
  • His invitation is to have all sins and mistakes washed away.
  • God is closing in on us.
  • And perceiving it…we will clear the air…straighten our paths and get in closer fellowship.

I knew a Lutheran minister who spent every Friday night in a dingy bar.

  • He did not go there to drink…but to spend time with people.
  • It was unnerving…especially for those who had been his confirmation students.
  • They had gone out for a night on the town.
  • And when the pastor walked in…the patrons always grew quiet.
  • A few slipped out.
  • Others laughed and turned away.
  • But many found him easy to talk with.

He told me: I discovered that if I go to them…they admit on Friday night what they would never confess on Sunday morning.

  • If they trust me…if they sense that I come in the name of a God who accepts them as they are…
  • Some of them take amazing steps in response to God’s love.
  • Now…this is the very definition of repentance.

But what about that brood of vipers?

  • This is John the Baptist’s critique of the religious leaders who joined the crowds for his baptism.
  • These were the Pharisees and Sadducees…easily identified by their elaborate clothing.
  • Curious…isn’t it…that they were attracted to John’s message?
  • Was it the spectacle?
  • Did they come out of curiosity?
  • Were they hungry for an encounter with the Holy?
  • We really don’t know.

What we do know is that John did not grant them special privileges.

  • The Pharisees were the Bible Keepers…guardians of morality… purists in every regard.
  • And they came to hear the preacher who dined on locusts.
  • The Sadducees were the high brows…the liturgical elite…the religious nobility…
  • And the families from which all the high priests were named.
  • Well…John would not give them an inch of preference.
  • He accused them of seeking baptism to slither out of hell.
  • Their privilege and celebrity were not enough to put them on the right side of God.
  • To paraphrase John: It does not matter who your ancestors were…you are all a brood of vipers.
  • His verbal ax struck at the root of their presumption.

So…here’s the thing: John was saying that nobody can fake the spiritual life.

  • Either we are living it…or we are not.
  • Either we are responding to God’s approach through a generous and holy life…or we are not.
  • Are we showing up only for the benefit of an appearance?
  • Or are we preparing a way for the Lord to reach our hearts…our souls…our minds…our strength?

Advent announces that God is drawing near.

  • Tugging at us to make a way for God to come closer…
  • Removing the roadblocks…straightening the highway…lifting the valleys and leveling the mountains.
  • No more faking it or putting on appearances…just being real.
  • This is our spiritual work for the season.
  • Replacing the artificial with the truth.

Advent invites us to surrender to God…which is always a surrender to grace.

  • We do not let down our guard because we fear that God will hurt us.
  • We let it down because God is moving toward us…
  • And God can heal us.
  • And God can make us new.
