Jesus demonstrated to the young ruler that he was a liar. That's why he went away in sorrow.I'm still waiting for someone to explain how any of that relates to the Savior's connection of keeping the commandments to eternal life:
Matthew 19:16-19---King James Version
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.
IOW--even if one believes the young ruler was a liar--God isn't. It was Jesus who gave the testimony found above--not the young ruler.
Next--how does anyone mesh the above testimony with Lutheran theology?
Read the section in Moses that begins Hear o Israel.
