let's look at the verses:
Luke 18:18-19 (YLT)
And a certain ruler questioned him, saying, `Good teacher, what having done--shall I inherit life age-during?' And Jesus said to him, `Why me dost thou call good? no one is good, except One--God;
Mark 10:13-18 (YLT)
And they were bringing to him children, that he might touch them, and the disciples were rebuking those bringing them, and Jesus having seen, was much displeased, and he said to them, `Suffer the children to come unto me, and forbid them not, for of such is the reign of God; verily I say to you, whoever may not receive the reign of God, as a child--he may not enter into it;' and having taken them in his arms, having put his hands upon them, he was blessing them. And as he is going forth into the way, one having run and having kneeled to him, was questioning him, `Good teacher, what may I do, that life age-during I may inherit?' And Jesus said to him, `Why me dost thou call good? no one is good except One--God;
Matt 19:13-17 (YLT)
Then were brought near to him children that he might put hands on them and pray, and the disciples rebuked them. But Jesus said, `Suffer the children, and forbid them not, to come unto me, for of such is the reign of the heavens;' and having laid on them his hands, he departed thence. And lo, one having come near, said to him, `Good teacher, what good thing shall I do, that I may have life age-during?' And he said to him, `Why me dost thou call good? no one is good except One--God; but if thou dost will to enter into the life, keep the commands.'
so obviously Jesus was fully human just as most Christians confess. in conclusion I sense that it is a similar vein of expression as:
Ps 73:1 (YLT)
A Psalm of Asaph. Only--good to Israel is God, to the clean of heart. And I--as a little thing, My feet have been turned aside,
Luke 10:19-22 (YLT)
lo, I give to you the authority to tread upon serpents and scorpions, and on all the power of the enemy, and nothing by any means shall hurt you; but, in this rejoice not, that the spirits are subjected to you, but rejoice rather that your names were written in the heavens.' In that hour was Jesus glad in the Spirit, and said, `I do confess to thee, Father, Lord of the heaven and of the earth, that Thou didst hide these things from wise men and understanding, and didst reveal them to babes; yes, Father, because so it became good pleasure before Thee. `All things were delivered up to me by my Father, and no one doth know who the Son is, except the Father, and who the Father is, except the Son, and he to whom the Son may wish to reveal Him .'
Matt 23:1-10 (YLT)
Then Jesus spake to the multitudes, and to his disciples, saying, `On the seat of Moses sat down the scribes and the Pharisees; all, then, as much as they may say to you to observe, observe and do, but according to their works do not, for they say, and do not; for they bind together burdens heavy and grievous to be borne, and lay upon the shoulders of men, but with their finger they will not move them. `And all their works they do to be seen by men, and they make broad their phylacteries, and enlarge the fringes of their garments, they love also the chief couches in the supper, and the chief seats in the synagogues, and the salutations in the market-places, and to be called by men, Rabbi, Rabbi. `And ye--ye may not be called Rabbi, for one is your director--the Christ, and all ye are brethren; and ye may not call any your father on the earth, for one is your Father, who is in the heavens, nor may ye be called directors, for one is your director--the Christ.
Matt 4:1-4 (YLT)
Then Jesus was led up to the wilderness by the Spirit, to be tempted by the Devil, and having fasted forty days and forty nights, afterwards he did hunger. And the Tempter having come to him said, `If Son thou art of God--speak that these stones may become loaves.' But he answering said, `It hath been written, Not upon bread alone doth man live, but upon every word coming forth from the mouth of God.'
