Matt 19:16-26
16 And, behold, one came and said unto him, Good Master, what good thing shall I do, that I may have eternal life?
17 And he said unto him, Why callest thou me good? there is none good but one, that is, God: but if thou wilt enter into life, keep the commandments.
18 He saith unto him, Which? Jesus said, Thou shalt do no murder, Thou shalt not commit adultery, Thou shalt not steal, Thou shalt not bear false witness,
19 Honour thy father and thy mother: and, Thou shalt love thy neighbour as thyself.
20 The young man saith unto him, All these things have I kept from my youth up: what lack I yet?
21 Jesus said unto him, If thou wilt be perfect, go and sell that thou hast, and give to the poor, and thou shalt have treasure in heaven: and come and follow me.
22 But when the young man heard that saying, he went away sorrowful: for he had great possessions.
23 Then said Jesus unto his disciples, Verily I say unto you, That a rich man shall hardly enter into the kingdom of heaven.
24 And again I say unto you, It is easier for a camel to go through the eye of a needle, than for a rich man to enter into the kingdom of God.
25 When his disciples heard it, they were exceedingly amazed, saying, Who then can be saved?
26 But Jesus beheld them, and said unto them, With men this is impossible; but with God all things are possible.
This passage actually is teaching the Truth that Jesus is God ! Notice vs 17 As the young man had addressed Jesus as good, and Jesus responded accordingly, why callest thou me good, for none is good but ONE, that One Being God
Now , notice Jesus did not say, none is good but One and that is my Father, but He said that One, Being God !
Now if Jesus by this is not insinuating that He is God, then the alternative is that He was not good, seeing He just said only ONE, not Two, but ONLY ONE is good.
Now, if Jesus was not good, being that He was not the Only One Good God, then His commanding him, the young ruler, in order to be perfect, that he must go sell all his possessions, then give to the poor, and follow Him; Such an commandment exposed that the young man loved his possessions above God, which was a violation of the very first commandment, now if Jesus was not God, then the young mans refusal to obey and follow Jesus, could not be a proper standard to gauge his Love to God !
For there could not have been nothing amiss about not making such a great sacrifice as that Jesus told him, and then following Him if the One speaking was not the One God, who Only was good !
