Key points

1The gospel is not only about how to get to heaven — it is about how life should be lived right now.
“the gospel is about how life should be lived right now”

2Ishmael represents slavery to self-effort; Isaac represents the freedom that comes from trusting God's impossible promise.

3When we get impatient with God's timing, we reach for the 'possible' route — which always promises much but pays off little.

4God is the God of the impossible — He parts seas, dries up rivers, and brings water from rock — and He calls us to trust that same power in our daily lives.
“You don't get to see water come out of a rock unless you're willing to walk into that desert with him”

5Mixing the world's gospel with the gospel of grace — letting grace cover eternity while living by the world's rules day to day — is a contradiction that will never produce what we truly long for.
“the grace gets me heaven when I die. The world's gospel is how I live here”
“God's not being mean, God's being loving”

6God's 'no' is just as loving as His 'yes' — Abraham's plea for Ishmael to be the promised heir shows how deeply we can cling to our own plan and resist God's better one.

7Christ has set us free — the call is to stay free and not return to slavery to law or self-made plans.
“it would seem that our Lord finds our desires not too strong but too weak. We are half hearted creatures, fooling about with drink and sex and ambition when infinite joy is offered us. Like an ignorant child who wants to go on making mud pies in a slum because he cannot imagine what is meant by the offer of a holiday at the sea. We are far too easily pleased”

Application
The sermon's 'so what' is a direct challenge to stop settling for the dog food of the possible and start trusting God's impossible promises in the concrete details of daily life — money, relationships, sexuality, time, and identity. The pastor frames this as a two-step response: first, recognize that mixing the world's gospel with genuine faith is self-defeating and will never produce the life God designed for you; second, take God at His Word and step into the desert with Him, because that is the only place where you will see seas part and water come from rock. Practically, this means giving first fruits before fear dictates your budget, pursuing relationships that honor God's design rather than settling for convenience, and bringing your 'Ishmaels' — the plans you have loved and begged God to bless — back to Him with open hands. The pastor also points forward: walking this out requires the power of the Holy Spirit and the presence of God's people, so community is not optional.
