In Luke 17, the rich young ruler asked Jesus, “What must I do to inherit eternal life?” Jesus replies by saying that no one is good except God alone. You know the commandments: Do not commit adultery, do not murder, do not steal, do not give false testimony, honor your father and mother.
The young ruler responds by saying “All these I have kept since I was a boy.”
When Jesus heard this he said to him, “You still lack one thing. Sell everything you have and give to the poor, and you will have treasure in heaven. Then come follow me.”
When the ruler heard this, he became very sad, because he was a man of great wealth.
Today’s confession points us to this reality… God’s perfect law demands perfect obedience. Whatever good we think do in this life to fulfill God’s perfect law is tainted with sin… every good work that we do is merely fulfilling what God requires, so nothing we do can be called extra credit or bonus points to make up for past failures or earn us future glory eternal life.
Even as the rich young ruler thought “All these I have kept since I was a boy” Jesus points him back to the perfect law. We deceive ourselves if we think we can do over and above what God requires of us. In fact, we are merely doing our duty and we fall far short of God’s perfect standard.
We are reminded again that it is by God’s Spirit that we do good works and it is our abiding by faith in the perfect work of Jesus that makes us acceptable to God, not our works by themselves.
5. We cannot, by our best works, merit forgiveness for sin or eternal life at the hand of God. This is true because of the great disproportion between our best works and the glory to come, and because of the infinite distance between us and God. We cannot benefit God by our best works nor render satisfaction for the debt of our former sins, for when we have done all we can, we have done merely our duty and are unprofitable servants. This is because, insofar as they are good, these deeds proceed from the Spirit; and, insofar as they are done by us, they are defiled and mixed with so much weakness and imperfection that they cannot endure the severity of God’s judgment.
