9 The Lord is not slack concerning his promise, as some men count slackness; but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance.
English Standard Version
9 The Lord is not slow to fulfill his promise as some count slowness, but is patient toward you,Some manuscripts on your account not wishing that any should perish, but that all should reach repentance.
9 God isn't late with his promise as some measure lateness. He is restraining himself on account of you, holding back the End because he doesn't want anyone lost. He's giving everyone space and time to change.
New King James Version
9 The Lord is not slack concerning His promise, as some count slackness, but is longsuffering toward us, not willing that any should perish but that all should come to repentance.
New Living Translation
9 The Lord isn't really being slow about his promise, as some people think. No, he is being patient for your sake. He does not want anyone to be destroyed, but wants everyone to repent.
Had these scoffers considered the dreadful vengeance with which God swept away a whole world of ungodly men at once, surely they would not have scoffed at his threatening an equally terrible judgment. The heavens and the earth which now are, by the same word, it is declared, will be destroyed by fire. This is as sure to come, as the truth and the power of God can make it. Christians are here taught and established in the truth of the coming of the Lord. Though, in the account of men, there is a vast difference between one day and a thousand years, yet, in the account of God, there is no difference. All things past, present, and future, are ever before him: the delay of a thousand years cannot be so much to him, as putting off any thing for a day or for an hour is to us. If men have no knowledge or belief of the eternal God, they will be very apt to think him such as themselves. How hard is it to form any thoughts of eternity! What men count slackness, is long-suffering, and that to us-ward; it is giving more time to hisown people, to advance in knowledge and holiness, and in the exercise of faith and patience, to abound in good works, doing and suffering what they are called to, that they may bring glory to God. Settle therefore in your hearts that you shall certainly be called to give an account of all things done in the body, whether good or evil. And let a humble and diligent walking before God, and a frequent judging of yourselves, show a firm belief of the future judgment, though many live as if they were never to give any account at all. This day will come, when men are secure, and have no expectation of the day of the Lord. The stately palaces, and all the desirable things wherein wordly-minded men seek and place their happiness, shall be burned up; all sorts of creatures God has made, and all the works of men, must pass through the fire, which shall be a consuming fire to all that sin has brought into the world, though a refining fire to the works of God's hand. What will become of us, if we set our affections on this earth, and make it our portion, seeing all these things shall be burned up? Therefore make sure of happiness beyond this visible world.
