Jesus Expands these OT Ideas of Atonement and Forgiveness
Matthew 5:43 NRSVue
“You have heard that it was said, ‘You shall love your neighbor and hate your enemy.’
He teaches to love one’s enemies
He expounds this as bringing the kingdom
If we don’t forgive other’s our sins won’t be forgiven
Jesus the Mediator of a New Covenant
Hebrews 9:15 NRSVue
For this reason he is the mediator of a new covenant, so that those who are called may receive the promised eternal inheritance, because a death has occurred that redeems them from the transgressions under the first covenant.
