Crossfire is referring to James 1:21-25; for in verse 22 we are told to be a doer of the Word, not a hearer only, in verse 25 we are told that we are to look into the perfect law of liberty. This law of liberty is spoken by Paul in Galatians 5:13-14; it is fulfilling the whole law by love. What are good works, will we know we are not saved by our own works, but if one reads the verse following Ephesians 2:8-9, it states:
For we are His workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them.
Ephesians 2:10
So what are the good works of the Holy Spirit working though us?
Our labour of Love though the Spirit (Roman 5:5)
For God is not unrighteous to forget your work and labour of love, which ye have shewed toward His name, in that ye have ministered to the saints, and do minister.
Hebrews 6:10
For we see in James 2:8-26, that the work of faith is love (see also Galatians 5:6). IMO, this is also what John wrote in I John 3:16-18.
