DID PAUL TEACH A NECESSITY TO MAINTAIN GOOD WORKS?

EPHESIANS 2:10 NKJV
     For we are His workmanship, created in Christ Jesus for good works, which God prepared
beforehand that we should walk in them.

2 TIMOTHY 2:21 NKJV
     Therefore if anyone cleanses himself from the latter, he will be a vessel for honor, sanctified
and useful for the Master, prepared for every good work.

2 TIMOTHY 3:16-17 NKJV
16   All Scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for
correction, for instruction in righteousness,
17   that the man of God may be complete, thoroughly equipped for every good work.

TITUS 2:7 NKJV
     in all things showing yourself to be a pattern of good works; in doctrine showing integrity,
reverence, incorruptibility,

TITUS 3:5,8 NKJV
5    not by works of righteousness which we have done,...
8    This is a faithful saying, and these things I want you to affirm constantly, that those who have
believed in God should be careful to maintain good works. These things are good and profitable
to men.

HEBREWS 13:20-21 NKJV
20   ...through the blood of the covenant,
21   make you complete in every good work to do His will, working in you what is well pleasing
in His sight, through Jesus Christ, to whom be glory forever and ever. Amen.
