I get what you are saying, but Jesus did not discuss this very salient point of doctrine at a most important moment in the history of the world;
which would make Jesus a weird liar, committing a sin of trickery and omission...
by purposely leading His disciples to think he was “just me myself” in human form but deceitfully omitting the specific word “blood” from what He did actually say:
See my hands and my feet, that it is I; touch me and know that a ghost does not have flesh and bones, as you see that I have.
Look at my hands and feet, and see that it’s really me. Touch me, and see for yourselves. Ghosts don’t have flesh and bones, but you can see that I do.”
See My hands and My feet, that it is I Myself; touch Me and see, for a spirit does not have flesh and bones as you see that I have.
Behold my hands and my feet, that it is I myself; handle me and see, for a spirit does not have flesh and bones, as ye see me have.
See my hands and feet, that it is I myself; handle, and see: for a spirit hath not flesh and bones, as you see me to have.
THE WORD OF GOD tells you flesh and blood cannot inherit the eternal life, but you spit on that because God has not supported your opinions! I leave you to the deception in which you are wallowing so proudly.
What do you think Jesus was referring to when he asked His disciples to look at and touch His hands and feet, just the fact He had hands and feet? He was referencing the fact the wounds of the crucifixition were still present, not healed or even closed. He had Thomas place his hand in His side wound where the Roman soldier had thrust the lancia.
Jesus is not giving the an anatomy lesson. He is not recapitulating Biblical lessons from Genesis where it was revealed that Life is in the blood. He knew they already knew that.
The Bible also says that it is not a complete record of everything that Jesus said and did, so dont assume that it has to be the complete record of what Jesus said and did or Jesus is being deceitful. It is not so he is not. There is no error of omission, because some things are just assumed to be known as true by everyone and dont need to be said.
