I was married for many years, and one of the accusations the ex threw at me constantly was “You are just Catholic. You confess something, and you do it again”. Well, she was right: like all of us I have habits of sin that I struggle with. They do not go away as you get older. But she is wrong.
For here the reformed agree with the Papists. We are all fallen. Our hope is not in what we do, for we will only be able to reform ourselves by the work of the spirit. We need to continually turn to the cross for this is our hope.
26For if we willfully persist in sin after having received the knowledge of the truth, there no longer remains a sacrifice for sins, 27but a fearful prospect of judgment, and a fury of fire that will consume the adversaries. 28Anyone who has violated the law of Moses dies without mercy “on the testimony of two or three witnesses.” 29How much worse punishment do you think will be deserved by those who have spurned the Son of God, profaned the blood of the covenant by which they were sanctified, and outraged the Spirit of grace? 30For we know the one who said, “Vengeance is mine, I will repay.” And again, “The Lord will judge his people.” 31It is a fearful thing to fall into the hands of the living God.
32But recall those earlier days when, after you had been enlightened, you endured a hard struggle with sufferings, 33sometimes being publicly exposed to abuse and persecution, and sometimes being partners with those so treated. 34For you had compassion for those who were in prison, and you cheerfully accepted the plundering of your possessions, knowing that you yourselves possessed something better and more lasting. 35Do not, therefore, abandon that confidence of yours; it brings a great reward.36For you need endurance, so that when you have done the will of God, you may receive what was promised.
The question of what willingly persist in sin means needs unpacking. None of us is righteous — we need to choose today to do good (but we cannot undo the wrong we did yesterday). And we all have error, and we need to take sin seriously and keep short accounts of our sin.
But Christ accepts us as we are. We need to change, but this is to please him. This is why confession requires repentance and contrition. It is not cheap, it is costly. And if we fail… we pray that instead of condemning us, our brothers and sisters will pick us up. So we hold to the faith we have been given, at such great cost.
