Where Certainty and Mystery Meet
This sermon explores the beautiful tension at the heart of prayer—a space where bold confidence in God’s love meets the mystery of God’s ways. Drawing on Psalm 138, Abraham’s prayerful bargaining, and Jesus’ teaching in Luke 11, it reminds us that prayer is not about having all the answers, but about trusting the One who hears. In joy or grief, with clarity or questions, we are invited to keep asking, seeking, and knocking—because God is good, and that is enough.

St. Augustine of Hippo is credited with saying something along the lines of: “Whenever you think you understand God,
you can be sure it’s not God you understand.”
And yet, how strange and wonderful it is that Jesus invites us— commands us, even—to pray.
To say “Father.” To say “Your kingdom come.” To ask. To seek. To knock.
Prayer is rooted in faith.
It’s where certainty and mystery meet.
It is as simple as a child asking to win a soccer game,
and as deep as present, grieving silence.
It is what we do when we’re full of joy and when we’re desperate for answers. Prayer lives in that holy tension between what we know for sure— and all that we will never understand.
Psalm 138 is a song of assurance and praise. Listen again to how it begins: “I give thanks to you, O Lord, with my whole heart…
[for] your love and faithfulness…”
There is certainty in this prayer. Certainty of God’s goodness.
The psalmist is not guessing about God’s love—it is unquestionable. The psalmist is not wondering if God hears—
“when I called, you answered me.”
This is one piece of prayer: confidence.
There are things we can say about God with boldness,
not because we figured them out,
but because God has revealed them in the stories of scripture and in our life experiences:
God is faithful. God is loving. God draws near to the lowly.
God does not abandon God’s work in the world.
There are certainties we carry with us into prayer.
And because of them, we can do what Jesus tells us to do in Luke 11: Ask. Seek. Knock.
Not because prayer serves as a kind of vending machine.
Not because God responds like some genie.
But because Jesus is describing the character of the One we pray to: A God who is like a loving parent.
A God who provides out of God’s goodness.
A God who longs to be known, who desires right relationship.
But alongside that certainty, there is always mystery.
Think of Abraham in today’s Old Testament reading.
It’s such a strange, tender, almost comical moment.
Abraham, standing before God,
bargaining over the fate of the cities of Sodom and Gomorrah: “What if there are 50 righteous folks? 45? 40? 30? 20? 10?”
He keeps asking, and God keeps listening and responding.
It feels bold, maybe even presumptuous. And yet, Abraham is deep in prayer. This is prayer at its most mysterious.
Abraham steps into a conversation where the stakes are cosmic and the outcome uncertain.
He doesn’t fully understand what God is going to do.
But he trusts enough to keep asking.
He knows God is just,
but he doesn’t always know how justice and mercy will shake out. We feel the same tension in our prayers:
we ask for healing—but don’t know when or how it will arrive. we ask for peace—but the world remains saturated in violence. we pray for clarity—and often find only more questions.
And yet…we pray.
This is the life of faith: to live in the space between certainty and mystery. Certainty gives us the courage to speak.
Mystery keeps us humble, listening, receptive.
Certainty reminds us that God is good.
Mystery reminds us that God is God.
That’s why the Lord’s Prayer matters.
It’s a map we return to when we’re not sure how to speak.
It teaches us the shape of faithful prayer:
“Our Father”—we belong to God.
“Your kingdom come”—we are not in charge.
“Give us…”—we can ask.
“Forgive us…”—we are always in need.
“Deliver us…”—we live with suffering, but not without hope.
Today’s Gospel reading ends with a striking promise:
“How much more will the heavenly Father give the Holy Spirit to those who ask!” The Spirit is not just the answer to our prayers—it is the means of our praying. The Spirit holds our words, our groans, our praises,
our silences, our stumbling prayers.
The Spirit allows us to live faithfully in the tension—
holding on to the certainty of God’s love
while being held by the mystery of God’s ways.
Don’t be afraid to pray, even when you don’t know what to say. Don’t be afraid to question, like Abraham.
Don’t be afraid to ask, seek, knock.
For the One who formed you in mystery has spoken to you in love. And that is enough to keep praying.
Let us pray.
Generous God who answers when we call,
who listens when we question,
who gives good gifts to those who ask—
bless us with bold and faithful hearts,
hearts full of wonder,
hearts full of trust,
hearts that never stop praying.
Amen.
