(32) And ye shall know the truth.--In the great Intercessory Prayer of John 17, Jesus prays for His disciples: "Sanctify them in the truth: Thy word is truth" (John 8:17). In the answer to the question of Thomas in John 14, He declares, "I am the way, the truth, and the life" (John 8:6). It is this thought that is present in the connection between continuance in His word and knowledge of the truth here. These Jews professed to know the truth, and to be the official expounders of it. They had yet to learn that truth was not only a system, but also a power; not only something to be written or spoken, but also something to be felt and lived. If they abide in His word they will indeed be His disciples; living the life of truth, they will gain perception of truth. "Being true," they will "in love grow up into him in all things, which is the head, even Christ" (Ephesians 4:15).

And the truth shall make you free.--Here, as in John 17:17, truth and holiness are spoken of as correlative. The light of truth dispels the darkness in which lies the stronghold of evil. Sin is the bondage of the powers of the soul, and this bondage is willed because the soul does not see its fearful evil. When it perceives the truth, there comes to it a power which rouses it from its stupor, and strengthens it to break the fetters by which it has been bound. Freedom from the Roman rule was one of the national hopes bound up with Messiah's Advent. There is indeed a freedom from a more crushing foe than the legions of Rome. (Comp. Mark 5:9; Luke 8:30.)

8:30-36 Such power attended our Lord's words, that many were convinced, and professed to believe in him. He encouraged them to attend his teaching, rely on his promises, and obey his commands, notwithstanding all temptations to evil. Thus doing, they would be his disciples truly; and by the teaching of his word and Spirit, they would learn where their hope and strength lay. Christ spoke of spiritual liberty; but carnal hearts feel no other grievances than those that molest the body, and distress their worldly affairs. Talk to them of their liberty and property, tell them of waste committed upon their lands, or damage done to their houses, and they understand you very well; but speak of the bondage of sin, captivity to Satan, and liberty by Christ; tell of wrong done to their precious souls, and the hazard of their eternal welfare, then you bring strange things to their ears. Jesus plainly reminded them, that the man who practised any sin, was, in fact, a slave to that sin, which was the case with most of them. Christ in the gospel offers us freedom, he has power to do this, and those whom Christ makes free are really so. But often we see persons disputing about liberty of every kind, while they are slaves to some sinful lust.And ye shall know the truth,.... Either the truth of the Gospel, the truth as it is in Jesus; meaning, that they should have a larger knowledge of it, while others are ever learning, and never come to the knowledge of the truth; but the spirit of truth should lead them into all truth, and cause them to grow and increase in Gospel light and knowledge; or Jesus himself, who is the way, the truth, and the life; and the sense is, that they should know more of him, of the dignity of his person, of the nature and usefulness of his offices; of the efficacy of his blood, the excellency of his righteousness, and the fulness of his grace, and that for themselves:

and the truth shall make you free; from ignorance and error, and the prejudices of education, under which the whole nation laboured, and from the thraldom of the law.
