The Covenant of Works means the judgment is strict.
Note that the New Covenant is also a covenant of works (Romans 2:6-8).
And its judgment is also strict (Matthew 12:36).
Indeed, even some Christians, at the judgment of the Church by Jesus Christ (2 Corinthians 5:10, Romans 2:6-8, Luke 12:45-48, Matthew 25:19-30), at His future, Second Coming (Psalms 50:3-5, cf. Mark 13:27), will lose their salvation because of such things as unrepentant sin (Luke 12:45-46, Hebrews 10:26-29; 1 Corinthians 9:27), unrepentant laziness (Matthew 25:26,30, John 15:2a, Romans 2:6-8), or apostasy (Mark 8:35-38, Hebrews 6:4-8; 2 Timothy 2:12b). That is why Christians know the "terror" of the coming judgment of the Church by Jesus (2 Corinthians 5:10-11), why they must remain in fear of being cut off the same as non-Christians if they do not continue in God's goodness (Romans 11:20-22, Luke 12:45-46), why they must be careful to work out their own ultimate salvation with fear and trembling (Philippians 2:12b; 1 Peter 1:17, Romans 2:6-8).

You need to perform everything perfectly.
Even under the New Covenant (Matthew 5:48).
For it is possible for Christians to be perfect (2 Timothy 3:17; 2 Corinthians 7:1; 2 Corinthians 13:11, Luke 6:40, John 17:23; 1 Corinthians 2:6, Philippians 3:15, Colossians 4:12, James 1:4).
For if we love God, we will obey Him (1 John 5:3, John 14:21-24). And if we obey Him, He will continue to love us (John 15:10).
And it is not difficult for Christians to obey everything that God requires of them (1 John 5:3b, Matthew 11:28-30, John 14:15,21, Matthew 5:48, Revelation 3:2; 2 Timothy 3:16-17, Colossians 1:28, Philippians 3:15; 1 Corinthians 2:6; 2 Corinthians 13:11).

The Covenant of Grace means judgment will be lenient.
So long as there is repentance if a sin is committed (1 John 1:9, Hebrews 10:26-29).
