(1) Modern Christian NT interpretation often overlooks a point well recognized by modern NT scholarship: that Paul's theological language often describes uplifting mystical experience. On this topic, Albert Schweitzer's old book "The Mysticism of Paul the Apostle" is a seminal classic. Once my Harvard NT professor, Dieter Georgi, was trying to nudge me away from an overly systematic and abstract view of Paul's epistles and cryptically said to me, "Mr. ___, you must remember that Paul likely wrote this in a crowded kitchen full of the smell of garlic. "
Paul urges us to walk in the Spirit, be led by the Spirit, and pray in the Spirit. Without detailing what each phrase means, I just want to draw attention to Paul's insistence that we routinely experience life in the Spirit rather than just try to apply dry biblical principles. Nowhere is this clearer than in Paul's disclosure of his disdain for attempting persuasive argumentation to make converts.
2 And so it was with me, brothers and sisters. When I came to you, I did not come with eloquence or human wisdom as I proclaimed to you the testimony about God. 2 For I resolved to know nothing while I was with you except Jesus Christ and him crucified. 3 I came to you in weakness with great fear and trembling. 4 My message and my preaching were not with wise and persuasive words, but with a demonstration of the Spirit’s power, so that your faith might not rest on human wisdom, but on God’s power (1 Corinthians 2:1-5)."
Paul wants his converts to base their faith on direct experience of the Spirit's power and guidance, not on an apologetically compelling faith! But Paul is well aware of our tendency to abandon our contemplative prayer life and replace it with doctrinal purity gained through debate and conflict. Listen to how he scolds the Galatians for their unhealthy shift of focus:
"You foolish Galatians! Who has bewitched you?...Are you so foolish? After beginning by means of the Spirit, are you now trying to finish by means of the flesh? 4 Have you experienced so much in vain—if it really was in vain? 5 So again I ask, does God give you his Spirit and work miracles among you by the works of the law, or by your believing what you heard (Galatians 3:1-5)?"
It is Paul's rich inner life, nourished by the fruit of the Spirit, that enables him to claim: " I have been crucified with Christ and it is no longer I who live, but Christ lives in me (2:20)."
Paul urges introspective self-examination to determine whether a believer's faith is real and an awareness of the indwelling Christ is an essential part of this testing: " Examine yourselves to see whether you are in the faith; test yourselves. Do you not realize that Christ Jesus is in you—unless, of course, you fail the testing (2 Corinthians 13:5)?"
My eventual provision of a methodology to experience the Spirit is intended by respect Paul's convictions on the ideal way for this to happen.
