God of peace, who brought again from the dead our Lord Jesus Christ, that great shepherd of the sheep, by the blood of the eternal covenant, make us perfect in every good work to do your will, and work in us that which is well-pleasing in your sight. Grant this through Jesus Christ the resurrection and the life, who lives and reigns with you in the unity of the Holy Spirit, God for ever and ever.
John 10:11-18 NAB
I am the good shepherd. A good shepherd lays down his life for the sheep. A hired man, who is not a shepherd and whose sheep are not his own, sees a wolf coming and leaves the sheep and runs away, and the wolf catches and scatters them. This is because he works for pay and has no concern for the sheep. I am the good shepherd, and I know mine and mine know me, just as the Father knows me and I know the Father; and I will lay down my life for the sheep. I have other sheep that do not belong to this fold. These also I must lead, and they will hear my voice, and there will be one flock, one shepherd. This is why the Father loves me, because I lay down my life in order to take it up again. No one takes it from me, but I lay it down on my own. I have power to lay it down, and power to take it up again. This command I have received from my Father.”
Acts 4:5-12 NIV
The next day the rulers, the elders and the teachers of the law met in Jerusalem. Annas the high priest was there, and so were Caiaphas, John, Alexander and others of the high priest’s family. They had Peter and John brought before them and began to question them: “By what power or what name did you do this?” Then Peter, filled with the Holy Spirit, said to them: “Rulers and elders of the people! If we are being called to account today for an act of kindness shown to a man who was lame and are being asked how he was healed, then know this, you and all the people of Israel: It is by the name of Jesus Christ of Nazareth, whom you crucified but whom God raised from the dead, that this man stands before you healed. Jesus is “‘the stone you builders rejected, which has become the cornerstone.’ Salvation is found in no one else, for there is no other name under heaven given to mankind by which we must be saved.”
