You identified Yourself as the good shepherd who cares for the sheep. You know the ones who are Yours, and they know You. They never follow another voice because all others lead to danger and death. Only with the Shepherd can they find safety.
In our day, so many people want to widen the gate. They may accept You, Jesus, as a good man, but they also welcome the other deities or rituals people rely on to try to get closer to You, claiming all efforts to reach God are equally worthy. But You say Your own sheep know better. They know the voice of their Shepherd who has told them there is only one way to the Father. We enter his grace through You alone. It is only in Your pastures that we find abundant and eternal life.
