In Luke 15, Jesus tells about a lost sheep rescued by the good shepherd. The parable teaches about God’s permissiveness, God’s love for individuals, God’s aggressive search, and God’s joy when a lost sheep is found.
In Matthew 13, Jesus compared Christianity to a man who found a valuable treasure in a field he was plowing. This parable shows the importance of the kingdom of God and why Jesus deserves full devotion. It shoots down the myth Christians shouldn’t be too dedicated to their faith.
