I've been thinking about idolatry and how that plays out in the lives even of Christians. John Calvin wrote about the propensity of all humans to hold on to idols in the heart (from Ezekiel).
This can be anything other than God. For example I wonder how easily the Republican Party (or Democratic Party) can become an idol. Or an ideology of what it ought to be. My country America, as great as it is, can surely become an idol, either rivaling or being too closely linked somehow in one's mind, to the kingdom of God.
How about one's ideal of what life ought to be? Now I tread softly and hopefully carefully here. Because we are dust and frail, and God knows that. And God says certain things are not good, for example it's not good for the man (or woman) to be alone. The answer there was the bond of marriage. But many who would like to be married, are not. And in the case of those who are married, they can so fawn over each other (fawing itself is good, by the way- one example) that they can end up making their marriage partner and marriage an idol. Remember, anything at all other than God, can become an idol.
The paradox is that as we learn to really put God first then the gifts of God can become more precious to us than ever. But when we put those gifts first, they eventually dry up, wither and die.
Much more to say on this. What would you like to add here?
