So down to the teaching – two chapters. Its a doddle really, the emotion of the book is in the part we have already read, Paul’s delight at how the truth has taken with them. This bit is sort of a “carry on!” pep talk.
We instructed you how to live in order to please God, as in fact you are living. Now we ask you and urge you in the Lord Jesus to do this more and more
First issue is sexual immorality, which may have been a pretty natural part of life for the Greek, idol worshipping community prior to conversion. He condemns it as bad faith towards others (taking advantage of a brother or sister) and God.
The immorality is an excess of lust to the extent that the body is controlled by it alone. It is a simple corollary of God calling us to holiness. Even if everyone consents, God hates it, because he has called us to be holy.
Consent can certainly be misleading as a test of morality. Sometimes it’s the lesser evil compared to say, social ostracism or loneliness. We’ve all known of consenting relationships that are bad ones. Paul is saying that at the base of sexual impurity is a lack of bodily control; of your own urges making you indifferent to the impact on others.
The alternate view is that the urge makes it right… To dump a family, to persuade someone to do something they would rather not, to live with someone who must put up with feeling unloved.
Is it faithless to want to understand gods rules? Jacob didn’t ask God why he wanted him to sacrifice his son. It’s tempting when debating issues such as sexual purity as a Christian to argue that God’s way is actually the best practical way to live in our world. But it often doesn’t ring true, the psalmists could see that.
The bible does often call us to feel like strangers in this world. I think the western church, as it’s cultural dominance wanes, is struggling with this. We are not used to feeling marginal. Arguing for sexual purity is increasingly awkward in this sex mad world. Though Paul is taking to believers here. The church is sufficiently marginal that there is no suggestion of any sort of influence in the wider cultural norms.
They don’t need to learn a thing, what praise! Just do what you are doing more and more. What does an ideal loving church look like? Here it is quiet and self reliant, quite surprising. Our love is what we should be known for, that is our advertising sign, our calling card and our cultural distinctiveness. Our teaching on sexual purity is for us.
