Being out of the UPC for over 10yrs, I'll give my observations once again. What do I miss from not being in the UPC? What I miss the most is the close fellowship with like-minded pastor friends.
That aside...
Good services? We have them.
Great music? We have it.
Anointed preaching? Have that too!
Awesome worship? Got it!!
Oneness teaching? Got it covered.
Gifts of the Spirit? Ditto.
Joy of the Lord? Bingo!!
Politics? Nada
Judgement? Zippo
Fear mongering? Zero!
We have folks who live over an hour away who attend NLC who used to be UPC. They attend because the oneness is very important to them, but they no longer want to get beat up with "sundry and various" extra-biblical requirements. Honestly, these are some of the most God-fearing folks among us!
All they want is to worship and serve God in freedom and liberty, not licenciousness and sin.
To some others, standards are so important that they will do almost anything to find a place where they are preached staunchly. I respect that as well. But that ain't us!
