For you were going astray like sheep; but are now returned to the Shepherd and Overseer{"Overseer" is from the Greek episkopon, which can mean overseer, curator, guardian, or superintendent.} of your souls.
Note 1.  In  1 Peter 2:24, Peter mentioned the fact of Christians "having died unto sins"; and there are a number of things which are included in the meaning: (1) There is preeminently the fact that Christ paid for us the penalty of death, which was due; and, the penalty having already been paid, it is legally true that all Christians are dead to sin.  Although his words here do not seem to be stressing this aspect of it, the whole context of the passage with its emphasis upon what Christ has done for us allows this meaning to come through.  (2) Christians are also dead to sin as far as their purpose is concerned.  The first impulse of the regenerated heart is the resolution to live above sin.  Therefore, as regards the purpose of Christians toward sin, they are dead to sins.  (3) As Macknight pointed out, from the viewpoint of the pagan world in which they lived, and in large measure the viewpoint of our own age, Christians are not available for the practice of sensuality, immorality and drunkenness expected of them in the secular society; and as far as that godless society is concerned, they are dead, being, to all practical purposes, dead to the popular practice of evil.  (4) One thing that is not meant is any implication that Christians are no longer tempted by sin.  Even Christ was tempted; and there is no state of sanctification or holiness which may be attained by a child of God that can free him from the temptations to which all flesh is heir.
