Talk about out of context. The author should read 1 Timothy 2:1-3 before citing verse 4. The “all men” in verse 4, in context, refers to men from all walks of life, not to each and every individual on the earth. Also, anyone who insists upon interpreting the “all” in 1 Timothy 2:4 to mean “each and every” must explain what happened to all that tax money the Chinese peasants paid when Caesar Augustus sent out a decree, “that all the world should be taxed” (Luke 2:1), and that “all [including each and every Chinese peasant?] went to be taxed” (Luke 2:3).
In 2 Peter 3:9, the “us-ward”, “any”, and “all” that Peter referred to are the saints of God, the elect. Peter’s epistles were written specifically to believers, as the first sentence of his second epistle (and first epistle as well) clearly states:
Simon Peter, a servant and an apostle of Jesus Christ, to them that have obtained like precious faith with us through the righteousness of God and our Saviour Jesus Christ: Grace and peace be multiplied unto you through the knowledge of God, and of Jesus our Lord
Therefore, Calvinists spin out abstruse and academic theories like Covenant of Redemption, the Covenant of Grace, Supra-infra-sub-lapsarianism, -- theories that are typically not arrived at by the typical believing student of the Bible. No, it takes theological eggheads the like late Augustine, John Gill, or Beza to develop and teach theories like these and teach them as biblical soteriology. The result is a loss of Biblical truth for some vain and extreme traditions of men.
Can't trust those dead white men. This is typical Christian anti-intellectualism. Read 2 Peter 3:15-18. Christian ignorance is not bliss.
Your interpretation makes the verse into a truism hardly worth uttering, much less interpreting.
