If salvation can't be lost, why do good works matter?

The short answer Settled

Because they are what God saved a believer for. Good works are the purpose of salvation, not its price.

Saved for good works

"For by grace you have been saved through faith, and that not of yourselves; it is the gift of God, not of works, lest anyone should boast. For we are His workmanship, created in Christ Jesus for good works, which God prepared beforehand that we should walk in them" (Ephesians 2:8-10).

Paul first shuts works out as the way of being saved. Then he gives them their place: God made the believer new for them. Christ "gave Himself for us," to make "His own special people, zealous for good works" (Titus 2:14).

A guitar is built to be played. One left in its case is still a guitar, but it is not doing what it was made for.

So it matters how a believer lives

Paul asks the question himself: "Shall we continue in sin that grace may abound? Certainly not! How shall we who died to sin live any longer in it?" (Romans 6:1-2). He tells Titus to "affirm constantly, that those who have believed in God should be careful to maintain good works" (Titus 3:8). The people told to maintain good works have already believed. A believer who neglects them does not lose his salvation, but he loses reward and meets the Father's discipline.

The usual objection

If salvation is a free gift that can never be lost, good works do not matter. A believer may live as he likes, and the more he sins, the more grace is shown.

Paul answers his own question: "Certainly not!" (Romans 6:2). The objection assumes that good works matter only if salvation depends on them. But God never asked for good works as the price of salvation, and He does not ask for them to keep it. He saved the believer so that he would do them. Christ "died for all, that those who live should live no longer for themselves, but for Him who died for them and rose again" (2 Corinthians 5:15).
