The Lord is my shepherd, I shall not want (Psalm 23:1). Give ear, O Shepherd of Israel, you who lead Joseph like a flock! (Psalm 80:1) We are his people, and the sheep of his pasture (Psalm 100:3). The Messiah is also pictured as the shepherd of God’s people: He will feed his flock like a shepherd, he will gather the lambs in his arms (Isaiah 40:11). Jesus says he is the Good Shepherd who will risk his life to seek out and save the stray sheep (Matthew 18:12, Luke 15:4). He is the Shepherd and Guardian of our souls(1 Peter 2:25)
Jesus made three promises to his followers. He promised them everlasting life. If they accept him and follow him, they will have the life of God in them. Jesus also promised them a life that would know no end. Death would not be the end but the beginning; they would know the glory of indestructible.
