Paul described himself as the Chief of Sinners. Yet, despite his great sin, God used him to spread the Gospel to the Gentile world.
The true identity of Jesus was not a well kept Secret. His claims to Messiahship and Deity enraged the unbelieving Jews in His day.
Jesus came first to the House of Israel, but there were other sheep in a different fold that He came for as well. He is the Good Shepherd of all Believers in the Church.
Jesus said, “I AM the Good Shepherd”. He alone lays down His life on behalf of the Sheep so that we may have life in Him.
