The shepherd, the divine life, and the human life are all for the flock. In verse 16 the Lord said, “And I have other sheep which are not of this fold; I must bring them also, and they shall hear My voice, and there shall be one flock, one shepherd.” Who are the sheep that are not of this Jewish fold? They are the Gentiles. And what is this one flock? The one flock signifies the one church, the one Body of Christ (Eph. 2:14-16; 4:6), brought forth by life, which the Lord imparted into His members through His death (John 10:10-18). Before, the fold was Judaism; now, the flock is the church. The sheepfold was, and still is, Judaism, but the flock is the church. The flock is the church which includes two peoples—the believing Jews and Gentiles. The Lord brings both together into one flock and under one shepherd. Now, the one flock and the one shepherd are the one Body and the one Head.
Why are the shepherd, the divine life, and the human life all for the flock? Because the people in the flock are fallen persons in need of redemption. As a man, the shepherd had the human life. He sacrificed His human life in order to accomplish redemption for His flock. In this way His flock was redeemed. Then His flock received His divine life, and by this divine life the sheep live together as the flock. Thus, the flock is formed into one unit, into one entity. This is not accomplished by the human life, but by the divine life.
In the human life we are condemned and divided; in the divine life we are accepted and united. In the divine life we are all one entity, meaning that we are one flock under one shepherd in one life. How good it is for brethren to dwell together in unity (Psa. 133:1). However, dwelling in unity simply means to dwell in the divine life. Praise the Lord that in the divine life we are truly one and love one another. This is not possible in our human, psuche life, but only in the divine, zoe life. We receive this zoe life through the redemption accomplished by our shepherd who laid down His psuche life. He sacrificed His psuche life to accomplish redemption for us all that we might receive Him as our zoe life. Now we are in the zoe life under one shepherd to be one flock. This is not an organization; it is a flocking together in life. It is wonderful. Hallelujah! The flock is not a matter of religion, but of life.
