Though, by the grace of God, I have received the great exchange of the gospel, I still participate, at times, in the grotesque exchange of Romans 1.
Those who profess to have wisdom often turn out to be, for the most part, foolish ...
But it is how this foolishness arises that is of interest to us. It is not because they profess to be wise that they are fools. Professing wisdom may be boastful, but it does not automatically make one foolish. No, Paul says that foolishness comes about because of an exchange.
We some times speak of "the great exchange" of the gospel: Christ became what he was not,so that we might become what we are not. He became sin, so that we might become righteous in him. This is the glory of the gospel.
The exchange that Paul speaks about here is not glorious or great, but grotesque. It is the quintessential perversion. Those who suppress the truth in unrighteousness "exchange the glory of the immortal God for images" (v. 23). Suppression of the truth reveals itself as idolatry.
(Oliphint, K. Scott. The Battle Belongs to the Lord: The Power of Scripture for Defending Our Faith. Phillipsburg, NJ: P&R, 2003. Print. 134-5)
I can be one who suppresses the truth of God while elevating myself, or some idol, in his place. Whenever I suppress the truth of the great and glorious gospel of God for the lies of sin, Satan, and this world I in fact exchange "the glorious exchange" for "the grotesque exchange".
And so I must continue to fight to behold the glory of God in the face of Christ that I might unmask this grotesque suppression of truth and lean into the glorious gospel and my great God.
