22 Although they claimed to be wise, they became fools 23 and exchanged the glory of the immortal God for images made to look like a mortal human being and birds and animals and reptiles. (Romans 1:22-23 NIV)
There are many things in this world we tend to put before God. Things that take up our time, our talents and our treasure. When we look at where we are spending these things we get a sense of the images we put before ourselves. The things we tend to hold up before God.
We exchange God’s glory and the immortal for the mortal.
