How do we know that the doctrine of Christ feeding His sheep is true?

The doctrine that Christ feeds His sheep is supported by biblical evidence and the historical accounts of the early church. In Acts 2, we observe the immediate fruit of Peter's sermon on Pentecost, where 3,000 souls were saved after he proclaimed Jesus' life, death, and resurrection as the cornerstone of their faith. Furthermore, the ongoing experience of believers today shows that those who call on the name of the Lord are indeed saved and experience spiritual nourishment through the Word and the sacraments. Hence, the feeding of the sheep is not a mere theory but a reality proven through the power of God in transforming lives.
