And Mat 7:21 points it out that good works do not save you, the people who say lord lord are they of their own good works, they do not abide in Jesus, if at all.
Your good works don't cut it, even the OT commandments don't cut it to get one into Heaven, No one went to Heaven until Jesus Did and they only did so because they were at his right hand not his left.
The ones who are on Jesus left are they who say lord lord but their hearts are far from Jesus and they do not abide in him, but abide in themselves and mans works, such have been payed and seen by men doing their own works.
Now what is wrong with doing your own good works is that does not cut it, because to claim such you are rejecting the Lord Jesus Christ as the Lord.
Mans works seeks it's own glory and they maybe good as such but they could be bad in the eyes of God too, just like Political Correctness may come across to fools as a good thing to idolise as many do but fact is when one truly understands it's workings then you can see it's of Satanic works, nothing to do with Jesus at all in anyway.
All Political Correctness works only to trump Christianity and once it has set it's self up truly, then it will stamp out Christianity, because Christianity does not cut it to the PC gods and such has been underway now for years undermining Jesus Christ.
All atheist love Political Correctness, it was the tool the Nazis and communist used to mislead the people and I am sure the people thought they were doing good like in that the ends justify the means crap. so they reject or turn away from Jesus Christ to do their own works because they don't believe that Jesus can cut it, so they think they have to add to Jesus their own works.
Jesus in Mathew 7:23 addressed the kind of people He was talking about.
Matthew 7:23 (KJV)
23 And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.
The word that is translated iniquity from the Greek is the word anomia, and means Lawlessness. But not lawlessness against man's laws but against God's/Jesus' words or commands. These are people like the pharisees seem to be rightious to others but they are living a lie.
But it doesn't mean that one is not required to have good works. It was part of the gospel Jesus preached.
Matthew 25:14-30 (NKJV)
14 "For
the kingdom of heaven is like a man traveling to a far country,
who called his own servants and delivered his goods to them.
15 And to one he gave five talents, to another two, and to another one, to each according to his own ability; and immediately he went on a journey.
16 Then he who had received the five talents went and traded with them, and made another five talents.
17 And likewise he who
had received two gained two more also.
18 But he who had received one went and dug in the ground, and hid his lord's money.
19 After a long time the lord of those servants came and settled accounts with them.
20 So he who had received five talents came and brought five other talents, saying, 'Lord, you delivered to me five talents; look, I have gained five more talents besides them.'
21 His lord said to him, 'Well
done, good and faithful servant; you were faithful over a few things, I will make you ruler over many things. Enter into the joy of your lord.'
22 He also who had received two talents came and said, 'Lord, you delivered to me two talents; look, I have gained two more talents besides them.'
23 His lord said to him, 'Well
done, good and faithful servant; you have been faithful over a few things, I will make you ruler over many things. Enter into the joy of your lord.'
24 Then he who had received the one talent came and said, 'Lord, I knew you to be a hard man, reaping where you have not sown, and gathering where you have not scattered seed.
25 And I was afraid, and went and hid your talent in the ground. Look,
there you have
what is yours.'
26 But his lord answered and said to him, 'You wicked and lazy servant, you knew that I reap where I have not sown, and gather where I have not scattered seed.
27 So you ought to have deposited my money with the bankers, and at my coming I would have received back my own with interest.
28 Therefore take the talent from him, and give
it to him who has ten talents.
29 For to everyone who has, more will be given, and he will have abundance; but from him who does not have, even what he has will be taken away.
30 And cast the unprofitable servant into the outer darkness. There will be weeping and gnashing of teeth.'
The unprofitable servant didn't use what he was given, so what he was given was taken away from him and given someone else.
In Mathew 7:24 Jesus made it quite clear that those who hear His words and do them are wise.
Matthew 7:24-27 (ASV)
24
Every one therefore that heareth these words of mine, and doeth them, shall be likened unto a wise man, who built his house upon the rock:
25 and the rain descended, and the floods came, and the winds blew, and beat upon that house; and if fell not: for it was founded upon the rock.
26 And every one that heareth these words of mine, and doeth them not, shall be likened unto a foolish man, who built his house upon the sand:
27 and the rain descended, and the floods came, and the winds blew, and smote upon that house; and it fell: and great was the fall thereof.
One of the things Jesus commanded His people to do is to use their gifts, and use of once's gifts is not limited to those in the Church. When Jesus went about healing people, He didn't exclude anyone when they came to Him for help.
Here the Galatians are encourged to not become weary in doing good.
Galatians 6:9-10 (KJV)
9 And let us not be weary in well doing: for in due season we shall reap, if we faint not.
10 As we have therefore opportunity, let us do good unto all
men, especially unto them who are of the household of faith.
