God has designed man with inner eyes. Psalm 121:1 tells the story of a man lifting up the inner eyes of his heart to the hills. Creation has given man an amazing testimony that utters speech and shows knowledge day after day (Psalm 19:2). Creation speaks to the moral conscience of man because he has these inner eyes. The heathen may look at the stars, the moon and the sun and marvel at the workmanship of God. He has a capacity for truth because he has been made with a moral conscience. As the heathen lifts up his inner eyes to the hills, the Holy Spirit witnesses to his heart the truth of God's character.
He realizes now that he should follow after what he sees. This is not worshipping creation or false gods, but it is honoring the Creator in truth. Salvation is truly of the Lord and a great work of God. The Holy Spirit has been poured out upon all flesh ( Joel 2:28) and is so available to witness to the heart of man the truth of God's character.
How often Christians are touched by God's ministry through creation? We worship the Creator as we gaze upon the beauty of the trees and the starry sky. We marvel at the power that holds it altogether, the mind that designed it all, and the amazing purpose that it all has. It is no wonder that the genuine reflection and humility in the heart of a man can lead him to the mystery of salvation as he lifts his eyes unto the hills. The hills just may be the stimuli necessary to establish our thoughts in the peacefulness of Who God is.
