Chapter XXXIII
Of the Last Judgment
I. God has appointed a day, wherein He will judge the world, in righteousness, by Jesus Christ,[1] to whom all power and judgment is given of the Father.[2] In which day, not only the apostate angels shall be judged,[3] but likewise all persons that have lived upon earth shall appear before the tribunal of Christ, to give an account of their thoughts, words, and deeds; and to receive according to what they have done in the body, whether good or evil.[4]
Westminster Confession of Faith
Chapter XVI
Of Good Works
...
VI. Notwithstanding, the persons of believers being accepted through Christ, their good works also are accepted in Him;[20] not as though they were in this life wholly unblamable and unreproveable in God's sight;[21] but that He, looking upon them in His Son, is pleased to accept and reward that which is sincere, although accompanied with many weaknesses and imperfections.[22]
VII. Works done by unregenerate men, although for the matter of them they may be things which God commands; and of good use both to themselves and others:[23] yet, because they proceed not from an heart purified by faith;[24] nor are done in a right manner, according to the Word;[25] nor to a right end, the glory of God,[26] they are therefore sinful and cannot please God, or make a man meet to receive grace from God:[27] and yet, their neglect of them is more sinful and displeasing unto God.[28]
On the one hand, the Confession summarizes the doctrine of Scripture to say all men will be judged based on what they have done. All are required to do "good" works, believers and unbelievers. WCF 33:1, summarizes Scripture to say all men will appear to do this- believers and unbelievers.
But only believers can indeed do good. (WCF 16:6)
On the other, it says that neglecting to do them at all is more sinful. (WCF 16:7)
We don't have a great deal of specificity, but we do understand a judgment (not the consequence of eternal damnation) for believers.
It might be more accurate to look at what a believer who does not do much "good" as losing reward rather than receiving punishment. I don't know. It's not the loss of salvation, but there are promises elsewhere of rewards in Heaven for some, in Heaven.
Salvation and being with God forever are wonderful enough, and it is, but there is even more. We just don't know much about it, it is reserved to the secret counsel of our God.
But we do know, there are rewards for obedience, and consequences for disobedience... even for believers.
