My brother-in-law is a self proclaimed atheist. Over the 30+ years I have known him, he and I have had wonderful discussions about our beliefs.
One time I was talking to him about the fruit of the Spirit (love, joy, peace, longsuffering, gentleness, goodness, meekness, faith, temperance).
Because natural men (those who are unbelievers, those who are not born again) have emotions which appear to be similar to the fruit of the Spirit (phileo love as opposed to agape love; happiness as opposed to true joy which only comes from a close relationship with Father God; periods where there is absence of conflict as opposed to the peace that passes all understanding which only our Lord and Savior Jesus Christ brings to us; etc.), my brother-in-law insisted that he knew exactly what I was talking about.
I explained to him that he did not because was not born again; his spirit was not yet renewed and he could not experience the fruit of the Spirit; that human emotion could not be compared to fruit of the Spirit.
He thought about it, and my brother-in-law finally had to admit that he did not know and he had never experienced the love of God which fills the heart of the believer; the effervescent joy and the peace which floods our soul even in the midst of turmoil.
Yes, these are the spiritual blessings the believer has in his or her life. These things are freely given to us by God. So, so sad that there are people who do not know the manifold wisdom of our glorious Father God.
