The parable of the lost sheep, also known as the parable of the strayed sheep, is found in both Matthew 18 and Luke 15. It is a story told by Jesus to convey an important lesson to us. In this parable, a shepherd leaves his flock of ninety-nine sheep to seek one that has gone astray. After finding it, he joyfully carries it back home and celebrates.

For Christians, this parable teaches about God's immense love and care for each individual person. Just as the shepherd seeks the lost sheep, God is always ready to seek and rescue those who stray from the right path. This shows that, to God, each person is valuable and important, regardless of how many others are on the right path.

Furthermore, the parable emphasizes the importance of reconciliation and forgiveness. The shepherd does not reprimand the lost sheep but welcomes it back with love. In the same way, God is always willing to forgive those who repent and return to Him.
