Your post is very telling of the chaos and constant splintering of the tens of thousands of Protestant sects.
Many of your sentences thoughts begin with I think or I donāt think/believe.
It doesnāt matter what Rev Kevin thinks or believes about anything - the TRUTH is all that matters.
You see - you DO need to belong to his ONE Body.
We ALL DO need to worship the same way because we are, as Paul says, "⦠one body and one Spirit, as you were also called to the one hope of your call; one Lord, one faith, one baptism; one God and Father of all, who is over all and through all and in all" (Eph. 4:4-6).
Paul goes on to say:
1 Cor. 11:2
"I commend you because you remember me in everything and maintain the traditions even as I have delivered them to you".
2 Thess. 2:15
"So then, brethren, stand firm and hold to the traditions which you were taught, whether by word of mouth or by letter from us."
2 Tim. 12:14
***"***Take as your norm the sound words that you heard from me, in the faith and love that are in Christ Jesus. Guard this rich trust with the help of the Holy Spirit that dwells within us."
**Finally **- at the Last Supper, Jesus fervently prayed to his Father in heaven:
***āI pray not only for them, but also for those who will believe in me through their word, ***so that they may all be one, as you, Father, are in me and I in you, that they also may be in us, that the world may believe that you sent me.
And I have given them the glory you gave me, so that they may be one, as we are one, I in them and you in me, that they may be brought to perfection as one, that the world may know that you sent me, and that you loved them even as you loved meā (John 17:20-23).
**In short - God DOES **care about how we worship and DOES want us to worship alike.
