Mr A and B and very close friends.

They are both a believer in the word of God but have quite a unique difference in how and ways they worship. Exodus 20:8 'Remember the Sabbath day, to keep it holy' It says....

Mr A strongly believe it's not compulsory to be in the church to honor that verse but paramount to make it holy by reading your bible, pray and probably watch a few bible sermons on the TV

while

Mr B strongly bible it paramount you are in the church irrespective of the fact that you might have read your bible, prayed or watched a few bible sermon on TV...

Which is right or wrong

Well, I believe it's their motive that matters. For example, the one that wants to stay back at home might want to have the quietness and personal space where he can be able to pour out his heart in praises and prayers just like Jesus went up the mountain in seclusion to pray to God shortly before he was betrayed. It's also possible that he really wants to stay behind because there is one football match or TV show he wants to watch or he wants to invite someone over (a babe) when everyone is out.

Also, the one that likes going to church might do so because he wants to learn new teachings from the sermon, or he wants to show one sister who he has been targeting since that he can speak in tongues and can quote bible passages all in the aim of wooing her.
