God told us everything we need to know to live as Christians. But what if the Bible doesn’t mention a particular topic? When we don't have clear instructions in the Bible, Christians we use principles from the Bible to make decisions. Let me give an example. The Bible doesn’t have a command telling us what day the church should gather. However, in the Bible, the first Christians gathered on The Lord’s Day or Sunday. Based on that example, the church I’m part of meets on Sunday. It’s not a sin to meet on another day because the Bible doesn’t give a command to meet on Sunday. But we’ve made a decision based on a principle that we find in the Bible.
