If someone takes a vacation, retires, or celebrates a birthday given your proclaimed beliefs, it isn't a sin since they have no choice in the matter, if they did, God's sovereign plan would be ruined.
Okay..say you went camping for a couple of weeks..Don't you know God can use you wherever you are?..Can we not witness on a boat or in a tent?..Going on "vacation " does not mean we are going without God, Lmo...
