You can get a PhD in Bible study but you don’t need a PhD to understand the gospel. Matter of fact, one of the largest reasons many people err with the scriptures (other than a blatant lack of study) is due to over-thinking them!
The existence of sin, the reality of the judgment and the possibility of salvation – which are all revealed through the cross of Christ (1 Corinthians 1:18, Acts 24:24-25) – isn’t hard to understand.
What muddies the clear waters of the gospel are “glasses” that refuse to see what God’s word reveals. These glasses can be political, intellectual, cultural, financial or denominational in nature, but regardless of the glasses’ nature, the result is the same … a departure from the wisdom of God (1 Corinthians 1:11-25). And this is why, when it comes to the essence of the gospel that God wants us to know about, the aforementioned glasses are excuses (and not reasons) for why we choose the wisdom of man instead of doing what God has commanded to be done.
“But I fear, lest somehow, as the serpent deceived Eve by his craftiness, so your minds may be corrupted from the simplicity that is in Christ. For if he who comes preaches another Jesus whom we have not preached, or if you receive a different spirit which you have not received, or a different gospel which you have not accepted—you may well put up with it!” (2 Corinthians 11:3-4 NKJV)
