Trinity: Why Do You Call Me "Good"?

Muslims like to bring up the incident where someone called Jesus "good" (here it is):

As Jesus was setting out on a journey, a man ran up, knelt down before Him, and asked Him, “Good Teacher, what must I do to inherit eternal life?”

Why do you call Me good?” Jesus asked him. 
“No one is good but One, that is, God.
--Mark 10:17-18

What Jesus is saying, then, is that this man was putting Him at the same level as God.
And Jesus is pointing this out.

For Muslims, this means that Jesus does not want to be called good because he is not God.

How should we as Christians say in reply?

What many people overlook is that Jesus taught against praising people, or receiving praise from others.  So what the man did by calling Jesus "good teacher" was contrary to what Jesus taught.
For example, let's read from Matthew's gospel:

“ But don’t you be called ‘Rabbi,’ for one is your teacher, the Christ, and all of you are brothers. Call no man on the earth your father, for one is your Father, he who is in heaven. Neither be called masters, for one is your master, the Christ. But he who is greatest among you will be your servant.  Whoever exalts himself will be humbled, and whoever humbles himself will be exalted.”
--Matt 23:8-12

So when the man addressed Jesus in a way that was contrary to what He taught, that really did require some response by Him.

But here is the real answer to the Muslim claim:  There are several passages that specifically mention that people worshiped Jesus, and in them, we never find that Jesus discourages this.
For example here is the passage where Jesus had healed a blind man on the Sabbath day:

"Jesus heard that they had cast him out, and having found him he said, 
‘Do you believe in the Son of man?’ He answered, ‘And who is he, sir, that I may believe in him?’ Jesus said to him, ‘You have seen him, and it is he who speaks to you.’ He said, ‘Lord, I believe’; and he worshiped him." 
--John 9:35-38

We see on the one hand Jesus teaching against receiving praise,
But on the other hand he allowed others to worship him.
We as disciples of Jesus do not believe that Jesus was a hypocrite,
so our only other explanation for this is that Jesus is,
in fact, God.

Another thing often overlooked is this:

After Jesus lists several commandments, he says:

He said to Him, “Teacher, I have kept all these from my youth.”
--Mark 10:20

In response, Jesus showed this person that his heart was spiritually not in the right place, because his riches were his idol:

“Go, sell all you have and give to the poor, and you will have treasure in heaven. Then come, follow Me.” But he was stunned at this demand, and he went away grieving, because he had many possessions.
--Mark 10:21
