Why are We Called All Sinners?: Why are all of us labeled as sinners, and yet many of us really choose to do the right thing? [Romans 7:15-25, I John 1:8-10, I John 2:1]. The Sin of Not Helping Others: If we see the needs of our neighbors, and refuse to help them, is that sin? [I John 3:17, Galatians 6:2].
