All I can see here is people making excuses of why they gather on Sunday, by the scripture they present. All they are doing is justifying why they gather on Sunday.
I am 27 yrs old, I was raised going to church on Sunday since I was about 5 yrs old. I was very knowledgeable about the scripture or so I thought. Everything that I heard I believed because it was instilled on me to be truth. When I read The Bible I understood it as how it was explained to me by my pastors, mother, throughout the years.
About four of five months ago, I started questioning everything that I understood to be truth, because things that I read in The Bible contradicted things that was instilled in me, for example, rapture pretribe, I've always believed The Ten Commandments applied to the church today but then there was that one commandment that didn't apply "Remember The Sabbath" and I never really questioned it. I would go to church on Sunday because my mother took me that day, because that is what I believed to be truth.
But since things were conflicting within me I was still seeking. Someone mentioned The Sabbath to me, presented scripture and it all started making sense. How can one ignore scripture and reject it. I was willing to put tradition aside for the truth.
I can understand many will feel dumb, believing that what they thought as the truth was actually deception, so I can see how many will not willingly admit they are wrong after so many years of tradition.
All I am saying is not to reject something that might bear truth, you don't want God to reject you.
