The testimony of Jesus concerning Himself: But ye believe not, because ye are not of My sheep, as I said unto you. V. 27. My sheep hear My voice, and I know them, and they follow Me; V. 28. and I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of My hand. V. 29. My Father, which gave them Me, is greater than all; and no man is able to pluck them out of My Father's hand. V. 30. I and My Father are one.
It was their unbelief that stood in their way, and this unbelief, in turn, proved that they did not belong to His sheep. Their unbelief in the face of such overwhelming testimony was their own fault.
For of His sheep, of the believers in Him, it was true that they heard His voice, as He had explained to them upon a former occasion. With His believers Jesus has entered into a close communion; He responds to their every need. And above all, He, as the Savior and powerful God, gives to them the life everlasting which He has earned for them by His atoning work.
No enemy in the world or elsewhere can rob them, can tear them away from Christ by any force. He has them firmly by the hand, He holds them safely in His hand, and therefore they shall never be lost.
The Lord here, as one commentator has it, gives us a guarantee against ourselves, against our own weakness and doubt. There are so many factors which tend to stifle faith in our hearts, to make us doubt the sincerity of God's promises toward us, but this word of Christ must overcome all doubt most effectually and definitely. Unless the believers maliciously reject their Savior and trample upon the salvation earned for them, there can be no doubt of His holding them in His hand. If we but trust in His loving mercy and kindness, there shall nothing harm us or tear us away from His side.
And this fact He emphasizes still more strongly by stating that the believers are given Him by His Father, who is greater and mightier than all; what enemy will tear them out of His Father's hands? God has given these sheep, these believers, to His Son, in order that they should be saved, and so they are kept by the power of God through faith unto salvation, 1 Pet. 1, 6.
And Jesus and His Father are one. There are two different persons, but only one essence. The will of the Son will never oppose the will of the Father. The Son is God just like the Father, and in the same degree as the Father. And from this it follows that the Father and the Son work together in this great work of saving men, of keeping the believers safe until the end.
Note: This glorious, comforting passage is of such beauty and power that it should be memorized by every Christian for use against the wily attacks of the devil and his allies. We are safe in the hands of our heavenly Father and of Jesus Christ. His Son, our Savior.
