So the works that will be tried by fire which a "works is represented by:
So the works you're talking about are the difference between ministerial works, that judged acceptable for reward or not, vs works that are judged good for life, or evil withd destruction.
1 Cor{3:10}
According to the grace of God which is given unto me, as a wise masterbuilder, I have laid the foundation, and another buildeth thereon. But let every man take heed how he buildeth thereupon... Every man’s work shall be made manifest: for the day shall declare it, because it shall be revealed by fire; and the fire shall try every man’s work of what sort it is. If any man’s work abide which he hath built thereupon, he shall receive a reward. If any man’s work shall be burned, he shall suffer loss: but he himself shall be saved; yet so as by fire.
Evil works we all know. Just read the law: Murder, theft, adultery, fraud, false witness, and such like. They are the works of the unrighteous that shall not inherit the kingdom of God.
Good works we also all know. Just read Jesus and James examples: Helping a person found injured on the road. Helping a known borther and sister in need immediate care.
Ministerial works, that are tried in the fire with reward or loss, we also know. Just read the doctrine of Christ by His apostles. If we testify of Jesus and teach the Scriptures well, then receive a reward. If we teach false doctrine and prophecy against Scripture, then we suffer loss.
The good news is that testifying and teaching well is simple: Just testify of Jesus as the Christ of God, and quote Scripture with it's simplest sense.
Ex:
1Pe 3:15
But sanctify the Lord God in your hearts: and be ready always to give an answer to every man that asketh you a reason of the hope that is in you with meekness and fear: Having a good conscience; that, whereas they speak evil of you, as of evildoers, they may be ashamed that falsely accuse your good conversation in Christ.
The good testimony of Jesus Christ is telling people that ask the reason for your life: Jesus is. Our goode conversation is godly living.
Rev 12:17
And the dragon was wroth with the woman, and went to make war with the remnant of her seed, which keep the commandments of God, and have the testimony of Jesus Christ.
Rev 14:12
Here is the patience of the saints: here are they that keep the commandments of God, and the faith of Jesus.
If we teaching keeping Jesus' commandments with godly living, we do well. If we teach any gospel and faith that justifies us without keeping God's commandment with godly living, we do not well.
Lastly, if our ministry by example and/or doctrine leads others into temptation and transgression, then our ministerial work is doing evil to others, for which we also shall be destroyed for defiling the temple and body of Christ with more ungodliness.
1 Cor{3:16}
Know ye not that ye are the temple of God, and that the Spirit of God dwelleth in you? If any man defile the temple of God, him shall God destroy; for the temple of God is holy, which temple ye are.
Rom 16:18
For they that are such serve not our Lord Jesus Christ, but their own belly; and by good words and fair speeches deceive the hearts of the simple. But shun profane and vain babblings: for they will increase unto more ungodliness.
2Pe 2:1
But there were false prophets also among the people, even as there shall be false teachers among you, who privily shall bring in damnable heresies, even denying the Lord that bought them, and bring upon themselves swift destruction.
