Build a firm foundation

Greetings:
Where is our foundation and on what is it built?
During my trips to the west coast, I have marveled to myself about all of those lavish multi-million dollar houses that were constructed on the edges of what we here in Indiana would call cliffs.
There were home after home perched on mountaintops with front yards overhanging into God's thin air.
I wondered why would anyone – even if you had the money – build a house situated in such a precarious position.
The slightest seismic shift, rumble or roar beneath the ground could surely send these huge, costly residences toppling to the ground below or into the ocean.
I guess it's all about foundation.
God warns us to build our lives on solid ground.  He also gives us many pieces of wisdom of how to build on solid ground in His Word.
Look at Luke 6:47, It reads: “Everyone who comes to Me and hears My words and acts on them, I will show you whom he is like:  he is like a man building a house, who dug deep and laid a foundation on the rock; and when the flood occurred, the torrent burst against that house and could not shake it, because it has been well built”.
But later in Luke 6:48-49 we are warned that there is a downside to seeing, reading and learning God's word and not acting on that knowledge
Luke writes: “The one who has heard and has not acted accordingly, is like a man who built a house on the ground without any foundation, and the torrent burst against  it and immediately it collapses, and the ruin of that house was great”.
So we are presented with our plan for this day and every day. We will make choices - some good and some not so good. 
Some of our choices will add mortar and strength to our foundation .
While other choices that are not so good will be as the rains that destroy the foundation, turning the soil to sand.
The question is, will we pick a path of thin foundation that can't stand firm in the time of trouble when the winds howl and the fire burns? Or, do we rely on God's Word to pave a firm path with a good foundation of truth and faith?
We have that choice.
Be blessed.
