“Be ye also patient,.... As well as the husbandman, and like him; and wait for the rains and dews of divine grace to fall, and make fruitful, and for the ripe fruit of eternal life; and in the mean while cheerfully and patiently bear all injuries, and oppressions: stablish your hearts; though the state of the saints is stable, they being fixed in the everlasting love of God, in the covenant of grace, in the hands of Christ, and on the rock of ages; yet their hearts are very unstable, and so are their frames, and the exercise of grace in them, and need establishing, which God's work; which is often done by the means of the word and ordinances; and these the saints should make use of, for the establishing of their hearts: the sense may be, take heart, be of good cheer, do not be dismayed, or faint, or sink under your pressures, but be of good courage, pluck up your spirits, lift up your heads: for the coming of the Lord draweth nigh; when he will render tribulation to them that trouble them, free them from all their sorrows and afflictions, and enter them into the joy of their Lord; which will be either at death, which was not very far off, or at the last day, which was drawing nearer and nearer, and which with God was near; with whom a thousand years are as one day.”

“Be ye also patient - Wait for God's deliverance, as ye wait for his bounty in providence. Stablish your hearts - Take courage; do not sink under your trials. The coming of the Lord draweth nigh - Ηγγικε· Is at hand. He is already on his way to destroy this wicked people, to raze their city and temple, and to destroy their polity for ever; and this judgment will soon take place.”

“coming . . . draweth nigh--The Greek expresses present time and a settled state. Pe1 4:7, "is at hand." We are to live in a continued state of expectancy of the Lord's coming, as an event always nigh. Nothing can more "stablish the heart" amidst present troubles than the realized expectation of His speedy coming.”
