Mt 9:12 On hearing this, Jesus said, “It is not the healthy who need a doctor, but the sick. 13 But go and learn what this means: ‘I desire mercy, not sacrifice.’ For I have not come to call the righteous, but sinners.”
We (Christians) tend to focus on the part about the healthy not needing a doctor – but only the sick. The part about mercy and sacrifice – I feel like we (Christians) tend to think this message was meant for the Jewish leaders – but not for us. Which is unfortunate.
