The Big “Why”?
Ultimately why do we buy the lie and get deceived by sin? As Christians who faithfully read and study God’s word and are acutely aware of the devastating effects of sin, why do we go ahead and throw caution to the wind and give in? At the deepest level of our hearts, it all boils down to our desires. We have been fooled that to desire sin is better than to desire Christ. We buy the lie that for the moment sin is all-satisfying instead of Jesus. Instead of seeing the beauty, majesty and excellencies of our Lord in His Person and work, we see the temporary joy that might come from indulging our flesh by sinning in rebellion against God. Our ultimate desire is for temporary pleasure instead of true lasting pleasure that only comes from Christ alone. C.S. Lewis captured this dilemma in his famous sermon “The Weight of Glory” when he writes, “We are half-hearted creatures, fooling about with drink and sex and ambition when infinite joy is offered us, like an ignorant child who wants to go on making mud pies in a slum because he cannot imagine what is meant by the offer of a holiday at the sea. We are far too easily pleased.”
The reason we are far too easily pleased is because we have been hardened by the deceitfulness of sin. We are content with the promise of temporary joy that comes from sin instead of finding our true contentment in the only One who can truly promise joy—eternal joy. Sin is a tricky foe that has resulted from a tragic fall. Sin is insidious. It is manipulative, devious, and never rests for a moment.
