The Lord is the door to the sheepfold. Originally, the fold was the law, and the Lord was the door into the law. The Lord was not only the door into the law; He is also the door for people to come out of the law. Verse 9 says, “I am the door; if anyone enters through Me, he shall be saved, and shall go in and go out and shall find pasture.” Christ is the door, not only for God’s elect to enter into the custody of the law, as did Moses, David, Isaiah, Jeremiah, etc., in the Old Testament time before Christ came; but also for God’s chosen people, such as Peter, James, John, and Paul, to come out of the fold of the law after Christ came. So the Lord indicates in verse 9 that He is the door not only for God’s chosen people to go in, but also for God’s chosen people to go out. Those who went into the law were people like Moses, the psalmists, and the prophets. Christ was the door for these people to go into the fold of the law. In other words, they went into the fold through Christ and for Christ. If we adopt this point of view when reading the writings of Moses, the psalmists, and the prophets, we will realize that they entered into the law of God through Christ. Christ was their entrance into the law.
At the time the Lord Jesus came, so many people were still in the fold. However, after the coming of Jesus, God no longer intended to keep His chosen people in the fold of the law. God wanted them to come out of the law into Christ. Thus, by that time, Christ no longer was the door for God’s chosen people to enter into the fold; He was the door for those who were already in the fold to come out. The blind man was one who was coming out of the fold. Formerly, all of the servants sent by God went into the law through Christ. But although Christ had come, the fold was still full of sheep who were confined within it. What should they do? They had to come out of the fold through Christ. During the Old Testament age, God sent many of His servants into the fold of the law through Christ. Now during the New Testament age, God intends to bring His people out of the law through Christ as the door.
