How does God warn us against sin?

God provides warnings against sin primarily through Scripture, which serves as our moral compass. The warnings in the Bible, such as in Deuteronomy 7 concerning marriage with unbelievers, highlight potential repercussions for disobedience. Additionally, God uses faithful pastors and teachers to convey these warnings, just as Kevin Thacker emphasizes in his sermon. These warnings are meant to protect us from harm and lead us to a life that reflects God's righteousness. Ignoring these warnings can have grave consequences as we see illustrated in biblical narratives.
