Sin grows up to become death.

Every sin is a soul killer and some sins are society killers.

To say sin doesn't matter is to ignore personal, spiritual health, the care and condition of society, the word of God, and the sacrifice of Jesus. That's an incredible list of things to ignore. 

But, God is good, too. 
That matters. 

In John 8, Jesus forgave the sinning woman, but told her to go and sin no more. In Luke 5, Jesus forgave the sins of a paralytic and healed him. Jesus never ignored sin. He loved people enough to die for sin -- to bear it on His body (see 1 Peter 2:24) -- that the power of sin and rule of Satan might be broken. We can honestly look at the bad news of sin AND be joyful about the good news of Jesus; we can do both. We can know the Savior who says "you are forgiven" and realize He is the same one who says "go and sin no more."

Same passage in the New King James Version

Today, just as a meditation, consider how Bro. James says sin comes about: "Blessed is the man who remains steadfast under trial, for when he has stood the test he will receive the crown of life, which God has promised to those who love him. Let no one say when he is tempted, 'I am being tempted by God,' for God cannot be tempted with evil, and he himself tempts no one. But each person is tempted when he is lured and enticed by his own desire. Then desire when it has conceived gives birth to sin, and sin when it is fully grown brings forth death." (James 1:12-15 ESV)

So, we see how sin is born. Now, we must agree with God about what is sin and what is not sin and enter the struggle with Him to put to death day-in-and-day-out the work and want of sin in our lives.
