1. God made everything to work perfectly under His loving rule (Romans 1:20).

[Sin is anything we think, say or do that rejects God or His instruction to us. It is self-centered rebellion toward God.]
3. Sin comes naturally to all of us (Romans 3:23).
4. Sin deserves God's judgement and our separation from Him (Romans 6:23).
