Build on the Rock (notes)

Reading: Luke 6.37-49
When Mainsell Investments began work on building what they hoped would be the world's tallest building in Brisbane, the first thing they had to do, after clearing the site, was to go down. The rail link between Central and Roma Street was closed for a weekend to construct a bridge for the line. This was so that further work could go ahead with foundations below that level.

I don't think we needed the distinction of having the world's tallest building. I do, however, regretfully agree that cities have to go up. The spread of cities over more and more qgricultural land represents poor planning for future generations. It happens so slowly - but sometime the red flag has to be waved.

Taller buildings mean more attention to foundations. You can't take a present building and add a further twenty stories - the foundations would not be adequate. The engineers have to do their calculations and tests and get it right the first time. It is a tragedy when a poorly built house collapses. It would be a disaster if a sixty-storey building fell.

In Jesus' time foundations were important too. The more familiar version of this saying of Jesus is in Matthew at the end of the Sermon on the Mount. There we find an additional element - the question of where the house is built. To build on the sand, on the flood plain, is to invite trouble - and even more so if you haven't dug proper foundations.

Here in Luke we have this saying at the end of what is called the Sermon on the Plain. The second man cuts his costs on foundations and is therefore able to produce a more imposing building. But it is a weaker building, not able to withstand the testing of the torrents.

The whole point of the parable is whether we hear the words of Jesus and do them. Can't you picture the crowd of people around Jesus? Lord, tell us another story? Lord, I need your help. Lord, did you hear about old Ezra the carpenter? Lord, I like what you say! Lord, thank you for answering my questions! And Jesus cuts across it all and says, "Why do you call me, 'Lord, Lord,' and do not do what I say?"

Doing what he says is the foundation. Not association with him, but faith in him. There are too many short-cut disciples. Their lives may appear impressive, but they fail at the point of obedience and that failure is evident in the time of testing.

How do we build our lives on the sure foundation?

  1. The secret of a strong and secure life is the Kingdom of God.
    The blessings and woes (vv.20-26) remind us that God is the final Ruler. We can only live under his forgiveness. That will be reflected in how we live.

  2. Life in the Kingdom will be expressed in love for enemies (vv.27-36).

  3. Love is not just an attitude, but will be expressed in an uncritical spirit (vv. 37-42).

  4. What we appear will be an expression of what we essentially are (vv.43-45)
    Where are our roots?

  5. Doing the words of Jesus involves - God's forgiveness, God's love within us practically expressed, his life coming to fruition in our lives.
