Refuge

Psalms 121:1-2 NIV
[1] I lift up my eyes to the mountains— where does my help come from? [2] My help comes from the Lord, the Maker of heaven and earth.
David found his hiding place within the mountains when he hid from Saul. He knew perfectly well how safe a cave could feel. Yet he reminds us here that his rescue did not come from the mountains. His safety and hiding place was in God.
Too often we find comfort in things of this world. In our jobs, in our studies, in health care, in our homes, so on. All these things are very good but they do not replace God. How often throughout the book of Isaiah did God warn the people about setting up thing as idols, about relying on earthly strength instead of on Him? Just like the Israelites then we seek strength for anything we can touch and see because we fear relying on God.
Yet David saw it. My safety is not from these mountains around me, my safety is from the God who made these mountains.
Our safety and strength and success does not come from anything we can touch or see, sure we will have put out effort on our part, but our salvation from all around us no matter what we face, is in God Himself.
These strongholds cannot save me, but God can!
