Matthew Poole and continuators on 2 Peter 3:9

9 The Lord is not slack concerning his promise, as some men count slackness, but is long-suffering to us-ward , not willing that any should perish, but that all should come to repentance.

I. e. Doth not defer the fulfilling of it beyond the appointed time, Isa. 60. ult.

Either the Scoffers here mentioned, who, because of Christ's not yet coming, questioned whether he would come at all; as if God had changed his purpose, or would not fulfil it: Or Believers themselves, who, through the weakness of their Faith, and greatness of their Sufferings, might grow into some degree of Impatience, and think Christ slow in coming to avenge their Cause, and give them their Reward. So much may be gathered from Rev. 6.10.

To us Believers, or us Elect.

Any that he hath ordained to Life, tho not yet called.

All whom he hath elected: he would have the whole number of them filled up, and defers the Day of Judgment till it be so: Or, this may be meant not of God's secret and effectual Will, but of his revealed Will, whereby he calls all to Repentance promiscuously that hear the Gospel preached, hath made it their Duty, approves of it, hath prescribed it as the way of Salvation, commanded them to seek Salvation in that way, and is ready to receive, and save them upon their repenting. See 1 Tim. 2.4.
