My wife is a Baptist, and I have heard quite a bit about this in our old Sunday school class…
More or less, the teaching starts with this:
For we are His workmanship created in Christ Jesus for good works, which God prepared beforehand so that we would walk in them. (Eph 2:10, NASB)
Because this mandates works, and we know that works can’t play a role in our salvation (…we do know that, right?), the works have to do something. Next, the teaching proceeds to this:
"But store up for yourselves treasures in heaven, where neither moth nor rust destroys, and where thieves do not break in or steal; *(Matthew 6:20, NASB)
knowing that whatever good thing each one does, this he will receive back from the Lord, whether slave or free.* (Eph 6:8, NASB)
and all of these:
1 Corinthians 9:25
And everyone who competes for the prize is temperate in all things. Now they do it to obtain a perishable crown, but we for an imperishable crown.
Therefore, my beloved and longed-for brethren, my joy and crown, so stand fast in the Lord, beloved.
1 Thessalonians 2:19
For what is our hope, or joy, or crown of rejoicing? Is it not even you in the presence of our Lord Jesus Christ at His coming?
Blessed is the man who endures temptation; for when he has been approved, he will receive the **crown of life **which the Lord has promised to those who love Him.
1 Peter 5:4
and when the Chief Shepherd appears, you will receive the crown of glory that does not fade away.
2 Timothy 4:8
Finally, there is laid up for me the crown of righteousness, which the Lord, the righteous Judge, will give to me on that Day, and not to me only but also to all who have loved His appearing.
Once they receive the crowns, however, there is some dispute as to whether or not they will keep them based on the following:
the twenty-four elders fall down before Him who sits on the throne and worship Him who lives forever and ever, and cast their crowns before the throne…
Basically, some of them (not necessarily all) say that God will give them to us, and in an as an act of humble and dutiful worship we will give them back to Him.
They all insist that it is neither selfish nor a works-including salvation system. If you try and go that route with them it will categorically fail. In my view, this is simply a means to reconcile all of the scripture passages that say we will be judged for our works while still having a system that is “faith alone”.
I think that sums up the position.
