Rocks can hurt if you walk on them barefooted. Rocks can make you stumble and fall if you aren't watching where you're going. Rocks can become a boundary for a garden or a path. Rocks can designate a border. Rocks can become walls that keep things in. Rocks can become walls that keep things out. Rocks can be stacked and staggered to build homes, roads, bridges and fortresses. Rocks can be so big that they are called mountains.
If you've ever traveled through the Rockies, seen the Alps or had the clouds roll back to blue skies on the day you visited Denali, you can imagine the Rock that David is describing here in Psalm 18:2.
Psalm 18:2 NLT
The Lord is my rock, my fortress, and my savior; my God is my rock, in whom I find protection. He is my shield, the power that saves me, and my place of safety.
In this verse David is singing a song of thankfulness to God the Rock. He has been saved and rescued from forces bent on his destruction. David praises God, his Rock, as his place of safety.
Run to the Rock who can transform a barrier into a blessing. The Rock who is able to shield the arrows of words and anger. The Rock who is a fortress against the angst of the world. The Rock who is our Cornerstone.
Acts 4:11 NLT
For Jesus is the one referred to in the Scriptures, where it says, ‘The stone that you builders rejected has now become the Cornerstone.’
A cornerstone is the single Rock that everything else is built upon. Jesus is our Cornerstone. When there is trouble (yes, there will be trouble) run to the Rock; Run to the Cornerstone.
