I think there should a "sometimes" option as well.
Therefore, to him who knows to do good and does not do it, to him it is sin.
James 4:17
I would have to wonder about person's motives/heart to follow holiness standards for 20 years then all of sudden feel that they are no longer necessary.. But then a person who has no knowledge or a limited knowledge of God to come into one of our churches repent, get baptized in Jesus' Name, and receive the Holy Ghost and then not follow our standards because of lack of understanding is completely different...
