Whatever we have given the highest honour to or the thing that is consuming our thoughts, resources,, activies or energies has become our object of worship. Whatever we've placed in that position will either propel us toward our intended created purpose or diminish our intrinsic value and worth that the Lord intends for us to live in. Gen 1:26-27 states that we have been formed in the image of God and that we are worship Him alone.
In Exo 20:3 the Lord specified in the Sinai covenant that Israel was not to wot sip any other gods before Him. While this could be interpreted that God is somehow insecure or needs ti be worshiped, i want to suggest that this condition was given to israel in order to protect and preserve their status as the pinnacle of Gods creative activity. They were being chosen to bear witness to nations what it meant to live in covenant relationship with Yahweh and this relationship would serve to entice all the nations to worship Him because of the benfits such a relationship afforded. As a good father, who desired the very best for his children, Yahweh was very aware of the danger idolatry posed in eroding their sense of personal value and worth.
Idolatry is the exchange of gods glory for a lesser glory. When our object of worship is lower than the lord we are in danger of diminishing and reducing our intrinsic value and self worth. Consider these words of the psalmist from Psalm 115:
"Their idols are made of silver and gold - they are man-made. They have mouths, but cannot speak, eyes, but cannot see, ears, but cannot hear, noses, but cannot smell, hands, but cannot touch, feet, but cannot walk. They cannot even clear their throats. Those who make them will end up like them, as will everyone who trusts in them."
The implication of these verse is huge - whatever we worship is what we ultimately become. Worshiping something less than the Lord actually pulls us away from our original created image. Our sense of identity and importance will never found in the resulting work of our hands. CS Lewis defined this sense of personal incompleteness as "the God-shaped hole" that exists in every person. Nothing that we can produce will ever provide the satisfaction we crave, the attention we desire or the sense of fulfillment all of us seek. As the psalmist understood, working to serve something less than the Lord pulls us even further away from the high place the Lord wants for us We are the only creatures in all creation made in the image of God. Let's ensure the Lord is the only object of our worship. Anything less than him will only undermine the intrinsic value we've been created in. In light of Psalm 115, the converse must also be true. If we worship the Lord alone, we'll begin to speak like He does, see like He sees, sense what He senses, walk how He walks. The prophet Ezekiel promised of a coming time where our hearts of stone would be replaced with a heart of flesh, a heart that beats in tune with God Himself. Establishing the Lord as the only object of our worship is what will cultivate and nuture this exchange of life.
