I Peter 2:24-25.
Who His own self bare our sins in His own body on the tree, that we, being dead to sins, should live unto righteousness: by Whose stripes ye were healed.
For ye were as sheep going astray; but are now returned unto the Shepherd and Bishop of your souls.
Peter quoted Isaiah 53:6 in v. 25. I always think of this classic picture that I remember from Sunday school many years ago. Jesus not only risked His life in our behalf. He gave up His life for us. He is The Good Shepherd.
I love these two verse. Peter, the hurly-burly fisherman, waxes poetic as he writes, showing us a side to his character that we tend to overlook.
We were indeed dead in our sin until Jesus came and bore the punishment of our sin in His own body. He was beaten mercilessly before He was nailed to His cross. It is through His suffering, death, and resurrection that we are healed from the results of our sin. We are to live righteously when we acknowledge Who He is and accept his gift of salvation.
He is the Shepherd. He is the Bishop (an overseer, a man charged with the duty of seeing that things to be done by others are done rightly) of our souls. He rightly claims that position because He gave His own life for ours.
