What kind of moron would take a map that was given to him and claim that, by following the directions, he had earned or merited the honor of arriving at the destination?

Thus Turretin:

THIRD QUESTION: THE NECESSITY OF GOOD WORKS
Are good works necessary to salvation? We affirm.

II. There are three principal opinions about the necessity of good works…; The third is that of those who (holding the middle ground between these two extremes) neither simply deny, nor simply assert; yet they recognize a certain necessity for them against the Libertines, but uniformly reject the necessity of merit against the Romanists. This is the opinion of the orthodox.

III. Hence it is evident that the question here does not concern the necessity of merit, causality, and efficiency—whether good works are necessary to effect salvation or to acquire it by right. (For this belongs to another controversy, of which hereafter). Rather the question concerns the necessity of means, of presence and of connection or order—Are they required as the means and way for possessing salvation? This we hold.

IV. Although the proposition concerning the necessity of good works to salvation (which was thrust forward in a former century by the Romanists under the show of a reconciliation in the Intermistic formula, but really that imperceptibly the purity of the doctrine concerning justification might be corrupted) was rejected by various Lutheran theologians as less suitable and dangerous; nay, even by some of our theologians; still we think with others that it can be retained without danger if properly explained. We also hold that it should be pressed against the license of the Epicureans so that although works may be said to contribute nothing to the acquisition of our salvation, still they should be considered necessary to the obtainment of it, so that no one can be saved without them–that thus our religion may be freed from those most foul calumnies everywhere cast mot unjustly upon it by the Romanists (as if it were the mistress of impiety and the cushion of carnal licentiousness and security)…

VII. And as to the covenant, everyone knows that it consists of two parts: on the one hand the promise on the part of God; on the other the stipulation of obedience on the part of man… [emphasis added].

Likewise we find in Benedict Pictet the same point:

As to the necessity of good works, it is clearly established from the express commands of God–from the necessity of our worshipping and serving God–from the nature of the covenant of grace, in which God promises every kind of blessing, but at the same time requires obedience–from the favors received at his hands, which are so many motives to good works–from the future glory which is promised, and to which good works stand related, as the means to the end, as the road to the goal, as seed-time to the harvest, as first-fruits to the whole gathering, and as the contest to the victory…

This sounds quite like what we find in the Westminster Confession on good works, as well as in Scripture.

Chapter 16:

These good works, done in obedience to God’s commandments, are the fruits and evidences of a true and lively faith: and by them believers manifest their thankfulness, strengthen their assurance, edify their brethren, adorn the profession of the gospel, stop the mouths of the adversaries, and glorify God, whose workmanship they are, created in Christ Jesus thereunto, that, having their fruit unto holiness, they may have the end, eternal life.

The Confession is translating the contemporary English translation of Romans 6.22. Here it is in context:

20 For when you were slaves of sin, you were free in regard to righteousness. 21 But what fruit were you getting at that time from the things of which you are now ashamed? For the end of those things is death. 22 But now that you have been set free from sin and have become slaves of God, the fruit you get leads to sanctification and its end, eternal life. 23 For the wages of sin is death, but the free gift of God is eternal life in Christ Jesus our Lord.

So the way is not a method of meriting, but a means of coming into possession.
