“Therefore . .” at the beginning of chapter 12 of Romans (we read Romans 12:1-8), Paul has completed his explanation of Christian “theory”. He will now turn to practical Christian living. But he makes it very clear that this is not detachable from what goes before. You can’t skip the first bit, because without it, this doesn’t make sense. It won’t even work.
Why is that? Surely Christianity is a very practical way of living? Yes, but it depends on God, faith, and grace. Without these, it fails. If you ask a question such as “What do I have to give God to get the thing I want?” there is no sensible answer. God doesn’t bargain. God gives generously, and includes us (if we are willing) in working for love, peace, justice . . But the good things you get are not your decision.
So – the section on practical Christian living starts with a call to be transformed. Yes, by all means be honest with God and express your hopes, desires and fears. But let the Holy Spirit get to work on you. Allow yourself to be changed, so that, gradually, you see more of God’s perspective on any situation. Don’t let yourself be bullied or manipulated into what is fashionable, or clever, or . . But look for what is good and sustainable. I don’t mean boring, or old-fashioned. There is plenty in God’s work that is exciting, creative, beautiful.
As your mind is re-shaped, (and yes, no matter how good your upbringing, we all need re-shaped minds!), look further. What gifts has God given you? There are lots of different ones, nobody has them all, but equally no Christian is left without a gift. What’s yours? Now, where does it fit in the Christian body? Paul gives a list, but there are other lists in other New Testament letters, and the wording varies, so there seems to be quite a variety. He wants to make the point that these gifts are not for “showing off”, as if believers were meant to be in competition for the “best” places. Quite the opposite, gifts are to be used for the benefit of the whole body – you use yours to help others, and need their gifts for the body to work as it should.
You can’t live as a Christian without being a Christian – because it only works if powered and directed by the Holy Spirit. Good intentions, discipline, duty – none are enough without the Spirit. That’s why the first steps involve a fundamental change of attitude, and being part of a co-operative, not competitive, group. And that is only the start!
