It matters very much what we do or do not do, but thankfully there is something else that matters most and that is what Jesus did for us. Sin is sin and it separates us from God and Ruins our relationships here on Earth and so it absolutely matters what we do. However, no matter what we do or how often we do it, Jesus is a friend of sinners. He Died for us and has provided a way out for us.
Readings: 2 Timothy 4:1-8, John 15:5-11
