I had a conversation recently with some friends and they asked how you discern the idols of your heart. We talk about this quite a bit at Revolution and what the gospel truth is. While there are some questions that others have developed that are very helpful, they pointed out that for them it seems to be a moving target.
One thing I pointed out that has helped me is discerning idols of the heart is what you doubt about God first or most.
For me, with a Reformed lens, I love the sovereignty of God. I rest in it, trust in it, believe in it wholeheartedly. It makes sense, I see it all over Scripture. It answers the deepest questions I ask. It is one of the easiest things for me to believe about God. When life does not go as I planned, seems out of my control, the sovereignty of God is the first thing I doubt.
Think about the approval idol. Someone who wrestles with this has a hard time believing they are loved by God. When they sin, the have doubts about God’s grace, forgiveness, that he will accept them in spite of their sin. They need to grow in God’s grace.
When it comes to comfort, in the moments of doubt and sin, those who struggle with this don’t believe God is good. They believe there is something else that is better than God in that moment.
