Verse 21. Neither part. You have no portion of the grace of God; that is, you are destitute of it altogether. This word commonly denotes the part of an inheritance which falls to one when it is divided.

Nor lot. This word means, properly, a portion which falls to one when an estate, or when spoil in war, is divided into portions, according to the number of those who are to be partakers, and the part of each one is determined by lot. The two words denote emphatically that he was in no sense a partaker of the favour of God.

In this matter. Greek, In this word, i.e. thing. That which is referred to here is the religion of Christ. He was not a Christian. It is remarkable that Peter judged him so soon, and when he had seen but one act of his. But it was an act which satisfied him that he was a stranger to religion. One act may sometimes bring out the whole character; it may evince the governing motives; it may show traits of character utterly inconsistent with true religion; and then it is as certain a criterion as any long series of acts.

Thy heart. Your affections, or governing motives; your principle of conduct. Comp.2 Ki 10:15. You love gold and popularity, and not the gospel for what it is. There is no evidence here that Peter saw this in a miraculous manner, or by any supernatural influence. It was apparent and plain that Simon was not influenced by the pure, disinterested motives of the gospel, but by the love of power and of the world.

In the sight of God. That is, God sees or judges that your heart is not sincere and pure. No external profession is acceptable without the heart. Reader, is your heart right with God? Are your motives pure -- and does God see there the exercise of holy, sincere, and benevolent affections towards him? God knows the motives; and with unerring certainty he will judge; and with unerring justice he will fix our doom, according to the affections of the heart.
