By St. Nikolai Velimirovich
"The Lord is not slack concerning His promise, as some men count slackness, but is long-suffering toward us, not willing that any should perish, but that all should come to repentance" (2 Pet. 3:9).
Brethren, the mercy of God delays "that day which burns like a furnace, according to the words of the Prophet Malachi" (Mal. 4:1). Therefore, let the scoffers be ashamed, who scoff at the promise of God and say: "Where is the promise of His coming?" (2 Pet. 3:4). God has not forgotten His promise but the sinners themselves have forgotten it. God, according to His immeasurable mercy, waits for the sinners to come to their senses, repent and to prepare themselves for that day which is not repeated. Behold that day is not like the many days which are given to men for the sake of repentance and to prepare for the encounter with God. That day is the only day and it differs from all other days, for it does not come for the sake of repentance but rather for judgment. Just as the Dreadful Judgment is only one and unrepeatable, thus is that day only one and unrepeatable.
