Can a person be saved and lose their salvation? The purpose of God's word is that we will not be confused, but that we would know the truth. The way we live communicates to others what we believe, therefore we all have an opportunity to preach the good news.
Is Jesus Christ the Lord and Master of your life?
Everyone, everywhere, has a since of right and wrong.
Everyone has failed to live up to God's standard.
If we are in Christ, it is our responsibility to warn people of God's wrath.
