What makes you think Paul is talking about a Jewish custom? Here is how Jewish Virtual Library describes the Jewish customs...
Jewish tradition requires men to cover the head as a sign of humility before God, and women, as evidence of modesty before men, although the Bible does not explicitly command either men or women to cover the head.
And not only is what Paul describes different from Jewish custom, it is also different from Greek and Roman customs as well.
It depends on what you mean by "heartfelt"... if somebody is not familiar with this scripture, I don't think it's held against them. But if someone's attitude in prayer is "Screw your customs Lord, I don't need a headcovering... oh by the way, give me my daily bread" I don't think it's going to go well for them.
Why? Where in the scriptures does it say you should do this?
No... no, it's not ridiculous. In fact there are very, very good reasons for those things in the scriptures.
I apologize for the late reply I didn't want you to think I was ignoring you. I may have things mixed up with my understanding of Jewish tradition so that I will take back
oh sorry for the bold letters it makes it easier to see for me.
But whether head covering or not really it comes down to prayer and how one should pray so lets go to the source Jesus himself he tells us exactly in the Lords prayer
Our Father, which art in heaven,
Hallowed be thy Name.
Thy Kingdom come.
Thy will be done in earth,
As it is in heaven.
Give us this day our daily bread.
And forgive us our trespasses,
As we forgive them that trespass against us.
And lead us not into temptation,
But deliver us from evil.
For thine is the kingdom,
The power, and the glory,
For ever and ever.
Amen.
Nowhere does he mention wearing anything you just speak to God. Prayer is now an open communication with God no rules or regulations Jesus broke all of that when he completed his fathers work on the cross the veil was torn when he resurrected and now we have a free and open commication and relationship with him so requiring to wear something to pray when after what Jesus did just doesn't make sense to me.
Also as for why I would not move not dare to speak or even look upon him that is what the fear of the Lord is. He is my savior my best friend the truth the way and the life but he is also my Lord and I don't take that lightly.
So for whatever reason he decided to show up and show me a taste of his Lordship. The intensity of his presence was a lot and you can feel so much in his presence the power and might that commands respect the authority he holds as king is unspeakable you can only have reverence for him you don't move your body isn't going to let you your like a small ant compared to him you instinctively show the utmost respect in that moment you don't speak unless he wants you to.
He did this not to scare me I actually was so thankful for it even as I was experiencing it but I always tell him he is my Lord and the term Lord is a heavy one not to be spoken lightly so perhaps he wanted to give me a taste of the Lord I serve
