Like I said, the KoG and KoH have most things in common.
Here is an example of a difference
Mat 25:14 For the kingdom of heaven is as a man travelling into a far country, who called his own servants, and delivered unto them his goods.
Mat 25:15 And unto one he gave five talents, to another two, and to another one; to every man according to his several ability; and straightway took his journey.
Mat 25:16 Then he that had received the five talents went and traded with the same, and made them other five talents.
Mat 25:17 And likewise he that had received two, he also gained other two.
Mat 25:18 But he that had received one went and digged in the earth, and hid his lord's money.
Mat 25:19 After a long time the lord of those servants cometh, and reckoneth with them.
Mat 25:20 And so he that had received five talents came and brought other five talents, saying, Lord, thou deliveredst unto me five talents: behold, I have gained beside them five talents more.
Mat 25:21 His lord said unto him, Well done, thou good and faithful servant: thou hast been faithful over a few things, I will make thee ruler over many things: enter thou into the joy of thy lord.
Mat 25:22 He also that had received two talents came and said, Lord, thou deliveredst unto me two talents: behold, I have gained two other talents beside them.
Mat 25:23 His lord said unto him, Well done, good and faithful servant; thou hast been faithful over a few things, I will make thee ruler over many things: enter thou into the joy of thy lord.
Mat 25:24 Then he which had received the one talent came and said, Lord, I knew thee that thou art an hard man, reaping where thou hast not sown, and gathering where thou hast not strawed:
Mat 25:25 And I was afraid, and went and hid thy talent in the earth: lo, there thou hast that is thine.
Mat 25:26 His lord answered and said unto him, Thou wicked and slothful servant, thou knewest that I reap where I sowed not, and gather where I have not strawed:
Mat 25:27 Thou oughtest therefore to have put my money to the exchangers, and then at my coming I should have received mine own with usury.
Mat 25:28 Take therefore the talent from him, and give it unto him which hath ten talents.
Mat 25:29 For unto every one that hath shall be given, and he shall have abundance: but from him that hath not shall be taken away even that which he hath.
Mat 25:30 And cast ye the unprofitable servant into outer darkness: there shall be weeping and gnashing of teeth.
The parallel passage is found in Luke 19
Luk 19:12 He said therefore, A certain nobleman went into a far country to receive for himself a kingdom, and to return.
Luk 19:13 And he called his ten servants, and delivered them ten pounds, and said unto them, Occupy till I come.
Luk 19:14 But his citizens hated him, and sent a message after him, saying, We will not have this man to reign over us.
Luk 19:15 And it came to pass, that when he was returned, having received the kingdom, then he commanded these servants to be called unto him, to whom he had given the money, that he might know how much every man had gained by trading.
Luk 19:16 Then came the first, saying, Lord, thy pound hath gained ten pounds.
Luk 19:17 And he said unto him, Well, thou good servant: because thou hast been faithful in a very little, have thou authority over ten cities.
Luk 19:18 And the second came, saying, Lord, thy pound hath gained five pounds.
Luk 19:19 And he said likewise to him, Be thou also over five cities.
Luk 19:20 And another came, saying, Lord, behold, here is thy pound, which I have kept laid up in a napkin:
Luk 19:21 For I feared thee, because thou art an austere man: thou takest up that thou layedst not down, and reapest that thou didst not sow.
Luk 19:22 And he saith unto him, Out of thine own mouth will I judge thee, thou wicked servant. Thou knewest that I was an austere man, taking up that I laid not down, and reaping that I did not sow:
Luk 19:23 Wherefore then gavest not thou my money into the bank, that at my coming I might have required mine own with usury?
Luk 19:24 And he said unto them that stood by, Take from him the pound, and give it to him that hath ten pounds.
Luk 19:25 (And they said unto him, Lord, he hath ten pounds.)
Luk 19:26 For I say unto you, That unto every one which hath shall be given; and from him that hath not, even that he hath shall be taken away from him.
The Matthew, the Lord gives talents, and the phrase Kingdom of Heaven is there.
Talents are a jewish currency. The foolish servant has his talent taken from Him and he is cast into outer darkness.
So, the main things in the Matthew parable are:
1. Jewish talents
2. Failure to increase results in damnation
The is the Kingdom of Heaven - Works based Salvation in the Millennial Kingdom (or it could possibly be the tribulation period).
The parable is Luke is notable for two things. It uses pounds, a gentile currency. The foolish servant is not condemned, but rather, the enemies of the Lord (those he went away for), are brought before him and slain.
So, the parable in Luke has
1. Gentile Currency (pounds)
2. Failure to increase results in loss of reward, but not damnation.
This is the Kingdom of God. Grace based salvation, rewards based on works.
