Yes, Jesus does believe lowly people are valuable. I believe Jesus during His ministry had a special affinity with people who were disadvantaged in the society they lived in. This is backed up by the accounts in the Gospel some of which are described in the lesson.

Jesus is as relevent now as He was then. He loves us all equally irrespective of our colour, age, sex, background, monetary wealth, etc. All we have to do to receive this love of Jesus is to open our hearts to Him.

Because if Jesus had condemned her he would have left the scibes and Pharisees unaware of their sins.

Jesus is more concerned with getting people to repent and stop sinning than condemning people for past sins.

The scribes and the Pharisees had no faith in Jesus, in fact they wanted to trap him - Jesus sees this as a greater sin than adultery.
