In Luke 15, when flagrant sinners came to Jesus to hear his teaching, he was severely criticized by the religious leaders of his day.
In response, Jesus taught three parables that reveal the seeking heart of God.
The first parable was about a lost sheep. Its shepherd left his flock to look for it, and when he found it, he carried it back on his shoulders, rejoicing. He then called his friends and neighbors to rejoice with him over his discovery.
