Matthew 13:11

He answered, and said unto them
Christ was always ready to give an answer to his inquiring disciples, concerning his ministry, and his conduct in it; which shows great respect to them, and condescension in him:

because it is given to you to know the mysteries of the kingdom of
heaven:
by the "kingdom of heaven", is meant the Gospel, which treats of the kingdom of heaven, and of things pertaining to it; of the saints' meetness for it, which is the regenerating and sanctifying grace of the Spirit; and of their right to it, which lies in the justifying righteousness of Christ. The "mysteries" of it intend the sublime doctrines thereof; such as relate to the Trinity of persons in the Godhead, to the incarnation of Christ, and the union of the two natures, human and divine, in him, eternal predestination, redemption by Christ, satisfaction by his sacrifice, justification by his righteousness, and pardon through his blood, the resurrection from the dead things, though clearly revealed, yet may have difficulties attending them, and which are not very easily solved: now to know and understand the great truths of the Gospel, spiritually, savingly, and experimentally, is not from nature, or to be acquired by men's industry, but is the gift of God's grace, flowing from his sovereign will and pleasure; a favour which the disciples of Christ, as a chosen people, receive from the Lord, and which is denied others:

but to them it is not given;
to the wise and prudent, to the Scribes and Pharisees, to the multitude, to the bulk and generality of the people, to the rest that were blinded. Mark calls them "them that are without"; who are not in the number of God's elect; nor within the covenant of grace, nor among the disciples of Christ; referring to a common way of speaking among the Jews, who used to call the Gentiles, all without their land, "they that are without"; and indeed all within themselves that despised the rules and judgment of the wise men ^F9: but Christ here calls the wise men themselves such. Now our Lord, who was privy to the secret and sovereign dispensation of God, who, of his own will and pleasure, had determined to give a spiritual and saving knowledge of divine things to some, and deny it to others, made this the rule of his conduct in his ministry; that is to say, he preached in parables to some without an explication, whilst he spoke plainly to others; and, if in parables, yet gave them an interpretation, and an understanding of them.
