Sheep Need The Good Shepherd

And when he went ashore he saw a great crowd, and he had compassion on them, because they were like sheep without a shepherd. Mark 6:34

All humans are to be compared to sheep, who without The Good Shepherd continue to go astray, each to his own way, and this leads to eternal death/separation from God and His blessings and protection. (Isaiah 53:6, John 10:26 and Proverbs 14:12) It is not flattering at all to be compared with sheep, for left to their own ways they end up either consuming poisonous food or water or being consumed by predators. Thus, the need for a Good Shepherd who can provide both wholesome food and water and protection.
The bible is full of such imagery of humans being sheep who have gone astray, each to their own way and thus in need of a Good Shepherd. This is none other than Jesus, who identifies Himself as such especially in John 10: "I am the good shepherd. The good shepherd lays down his life for the sheep."
Jesus' sheep are called by their name and placed into His flock at baptism through the power of His Holy Word and are kept following His voice only to eternal life. (John 10:22-30) There are only two flocks in reality, the flock who follows the devil and the flock who follows Jesus, The Good Shepherd.
Pastors are placed among the flock of the Holy Christian Church to shepherd Jesus' flock and lead them to eternal pastures so wonderfully espoused in Psalm 23. These under shepherds (see 1 Peter 5:1-4) speak on behalf of the Good Shepherd and speak not what the sheep want and like to hear (2 Timothy 4:3-4) and Jesus' sheep will not follow one of these false shepherds who will not speak the whole counsel of God's Word, nor warn and protect them from predatory teachings. (John 10:4-10) It does all come down to the pure teachings of the Bible, as Jesus in Mark 6 does just that after proclaiming that these sheep without a shepherd need to be fed, so he had Bible Study with them. (Mark 6:34b)
Following the voice of the Good Shepherd, Jesus, His sheep from the moment of faith have the life He came to give them (John 10:10, 28) and enjoy His goodness and mercy all the days of their lives, dwelling in His house forever. (Psalm 23:6)
