Your repeated anger leads to latent bitterness which leads to relationship-destroying gossip.
Your pornography-viewing leads to unmarital sex which leads to one parent raising a child in isolation which leads to crippling resentment.
Unchecked sin always spreads, and kills where it does. Like cancer.
But one of the beautiful mercies of God is that He has given us a community where sin and its scars can be dealt with.
Churches are little cities of imperfect people, people who have been miraculously remade and who, by the grace of a very real and very compassionate God, continually confess and continually turn from the sins they still commit. They know who they were (spiritually dead evil people), they know who they are (spiritually alive people being slowly made more and more like Jesus), and they know who God is (the Father, the Son, and the Holy Spirit who love to save sinners). And because of these 3 things, these little collections of Gospel people are able to bring wicked and broken and scared and angry humans into their midst and minister to them. Serve them. Help to stop the bleeding in their lives.
The world is home to all stripes of sinners who are in different stages of the pain or disarray or death that sin brings along as its trail. And there is no one else who can get to the root of the chaos or who can apply supernatural salve to the wounds of all this sin like the church can. She has been given the Good News that can heal and can save people from their evils, and from the evils that were committed against them. She can rescue them from the worst of the violence and the trouble and the affliction of this world.
Which is great, because this is not Mayberry. This is a world of adultery and ulterior motives and hearts who will cast those they love aside for pleasure or power. This is a world where sin has left some long, long shadows. Sons deserted by their fathers, marriages in flames because of selfishness, grown men and women who don’t know how to be men or women. And there in the heart of this world stands the church, giving the hope and the truth and the life that only she can give.
This world needs her. The single mothers and the heroin addicts and the workaholics and the shallowest of womanizers need her. She is a city on a hill.
She is where they can come for possibility. For hope. For adoption into a forever family. She is where they can sojourn for all of the things that only Jesus can hand over.
For everyone trapped in what sin has spoiled, churches are households of transforming mercy. They are families of forgiveness. They are little peoples of honest confession and honest love and honest Gospel.
This is a world of long shadows. Because sin never stops where it whispers it will. Sin never keeps that promise.
But the God of the Cross has given a light that can beat those shadows back. His church holds that light in her hands, for any and all to come see.
