What is distressing to me as one who has dedicated a life to the mission of the Gospel is how few Christians talk about sin anymore. Some Christians teach a lot about being born again, but I am not hearing that one needs to come to grips with his or her sin first. Other Christians teach a lot about inclusion, but I don't see much introspection about how our own sinfulness may be what is dividing our communities. Lot's of people are going to mega churches and following TV preachers to "find their best life now" or to get a "special blessing" and will sign up for seminars, buy books, and contribute money without doing the one thing that is actually necessary to actually turn their life around. Then I acknowledged my sin to you, and I did not hide my iniquity; I said, “I will confess my transgressions to the Lord,”and you forgave the guilt of my sin. Psalms 32:5 (NRSV)
Perhaps most distressingly, many of the right wingers and left wingers who are manning the barricades of the culture wars to right the wrongs of society are utterly blind to the fact that it is most often our own sin which obstructs us from building a more blessed and beloved community. It is not the sins of those whom we dislike that we need to deal with first, it is the sins committed by ourselves.
Don't get me wrong people believe in sin, it just that we like to look for it in others, not ourselves. This is the ultimate spiritual struggle and we are called to enter the fray. For until we experience forgiveness we will not be free and we will not be healed. Our created purpose is to be people at peace with God and the world and that can not occur until we are relieved of the burden of sin which weighs so closely.
The simple fact of the matter is that we cannot understand the true power of the Gospel unless we start to grasp what Christ has freed us from. Lutherans traditionally have always talked about the big three, sin, death and the devil. Notice which one is first. Sin leads to death and it leads us to open the door to evil in our lives. Confession and forgiveness is basically preventive medicine to help us be whole.
This leads us to be forgiving of others, because when we begin to understand that we are not perfect we can better appreciate that our neighbors, co-workers, classmates and family members are not perfect either. Two key outreach actions of the church in wider society are dependent on a healthy appreciation of our own sinfulness, evangelism and advocacy for the marginalized. In order to effectively reach out in both ways we have to appreciate our own history of sin, forgiveness, and new life, as well as our dependence on God to guide us when we do not know the way.

I understand our reluctance to talk about sin openly; it is certainly easier in the short run to avoid seeing that negative aspects of our lives. Some churches today don't really want to make people feel guilty by pointing out that its members are not perfect, so they avoid the topic. However, the Word is clear While I kept silence, my body wasted away through my groaning all day long. Psalms 32:3 (NRSV)
Guilt doesn't come from talking about sin; it comes from unresolved sin. The church that refuses to talk about sin is doomed experience it in soul crushing ways. When I fist figured out that God loved me even though I have done things that I should not have, I felt peace. I would never have experienced true peace for even a brief second if I had not talked to God about the truth of who I am. So I am making the case that we talk about sin, most importantly our own, so we can know the power of Christ who has forgiven us. So give me that old-time religion where sinners are forgiven and loved by a gracious God.
Be blessed
