See? Legalism views sin as a disease rather than a crime.
Matthew 22:1-14 KJV
And Jesus answered and spake unto them again by parables, and said, [2] The kingdom of heaven is like unto a certain king, which made a marriage for his son, [3] And sent forth his servants to call them that were bidden to the wedding: and they would not come. [4] Again, he sent forth other servants, saying, Tell them which are bidden, Behold, I have prepared my dinner: my oxen and my fatlings are killed, and all things are ready: come unto the marriage. [5] But they made light of it, and went their ways, one to his farm, another to his merchandise: [6] And the remnant took his servants, and entreated them spitefully, and slew them. [7] But when the king heard thereof, he was wroth: and he sent forth his armies, and destroyed those murderers, and burned up their city. [8] Then saith he to his servants, The wedding is ready, but they which were bidden were not worthy. [9] Go ye therefore into the highways, and as many as ye shall find, bid to the marriage. [10] So those servants went out into the highways, and gathered together all as many as they found, both bad and good: and the wedding was furnished with guests. [11]
And when the king came in to see the guests, he saw there a man which had not on a wedding garment: [12] And he saith unto him, Friend, how camest thou in hither not having a wedding garment? And he was speechless. [13] Then said the king to the servants, Bind him hand and foot, and take him away, and cast him into outer darkness; there shall be weeping and gnashing of teeth. [14] For many are called, but few are chosen.
Seems like Jesus answered your question. Here's another:
John 10:1-11 KJV
Verily, verily, I say unto you, He that entereth not by the door into the sheepfold, but climbeth up some other way, the same is a thief and a robber. [2] But he that entereth in by the door is the shepherd of the sheep. [3] To him the porter openeth; and the sheep hear his voice: and he calleth his own sheep by name, and leadeth them out. [4] And when he putteth forth his own sheep, he goeth before them, and the sheep follow him: for they know his voice. [5] And a stranger will they not follow, but will flee from him: for they know not the voice of strangers. [6] This parable spake Jesus unto them: but they understood not what things they were which he spake unto them. [7] Then said Jesus unto them again, Verily, verily, I say unto you, I am the door of the sheep. [8] All that ever came before me are thieves and robbers: but the sheep did not hear them. [9] I am the door: by me if any man enter in, he shall be saved, and shall go in and out, and find pasture. [10] The thief cometh not, but for to steal, and to kill, and to destroy: I am come that they might have life, and that they might have it more abundantly. [11] I am the good shepherd: the good shepherd giveth his life for the sheep.
