A scribe asks Jesus what is the greatest commandment. Jesus answers with two commandments:
1/ Love God with all your heart, mind, soul, and strength, and
2/ Love your neighbor as yourself.
The scribe says, yes, you are right. These are more important than all the burnt offerings and sacrifices.
Jesus says "You are not far from the Kingdom of Heaven."
This is some of the clearest information we get from Jesus about exactly what he was working for.
The Kingdom of Heaven is something very close to loving God, loving your neighbor as yourself, and recognizing that these are more important than following a complicated list of rules.
