Many natural theologians I’ve dialogued with have this false assumption that unbelievers can actually reason to God through man’s philosophical arguments that don’t even defend or argue for the Trinitarian God of scripture. The worst part is, the Bible is left out as the foundation.
Scriptures like 2 Cor 5:11 are commonly used as if Paul was using a non presuppositional approach to his apologetic. It is assumed that the persuasion is through Paul’s own ability to create and present arguments. Some people argue that, in Jesus’ day, it was by people’s own ability to see Jesus perform miracles, but if that were the case then ALL people who saw him would be believers. That clearly wasn’t the case.
2 Corinthians 5:11
Since, then, we know what it is to fear the Lord, we try to PERSUADE others. What we are is plain to God, and I hope it is also plain to your conscience.
It’s quite simple to see that it is God that gives people the understanding of scripture since the natural man can’t understand the things of God.
Then he (Jesus) opened their minds so they could UNDERSTAND the Scriptures.
It is God that reveals who the Son of God is and not flesh and bone.
Jesus replied, “Blessed are you, Simon son of Jonah, for this was NOT revealed to you by flesh and blood, but by MY FATHER IN HEAVEN.
Another false assumption is that an argument is supposed to actually convince an unbeliever that God exists. Scripture is quite clear that everyone knows His existence and is without excuse according to Romans 1. And again, the natural man cannot understand the things of God.
If natural theology is looking for an irrefutable argument that proves his existence, then that is quite simple. Here it is…
1) Nothing exists or God exists
2) Something exists
3) Therefore God exists.
There is no need to try to convince people of something that can be easily proven and that God says they have no excuse for rejecting. As a presuppositionalist in my apologetics, I can rest in God’s word when He says it is the Gospel that is His power to save those that believe. If any unbeliever wants to impose their secular philosophy or is sincerely asking me for an answer, then I will respond as God has directed us according to 1 Peter 3:15 and Proverbs 26:4-5.
Bottom line, it is God that saves through His Gospel and not our arguments.
