For this they are willingly ignorant.
When one spends anytime reading the bible, eventually one will begin reading certain portions of it over again. Being the living word that it is, often something new will hit you like a ton of bricks. This portion in 2Peter is one of those passages.
2Pe 3:3 Knowing this first, that there shall come in the last days scoffers, walking after their own lusts, 4 And saying, Where is the promise of his coming? for since the fathers fell asleep, all things continue as they were from the beginning of the creation. 5 For this they willingly are ignorant of, that by the word of God the heavens were of old, and the earth standing out of the water and in the water: 6 Whereby the world that then was, being overflowed with water, perished:
Peter starts off by telling us that there will be scoffers that will question the existence of God, or at least question His imminent return. I think it is fair to say that they question His existence altogether. “All things continue as it has since the beginning of [time].” Remember, they say this because they walk after “their own lust,” in other words, they wish to live their lives as if they aren’t really accountable to a higher authority.
“For this they are willingly ignorant.” Because the scoffers want to live their lives without God, they make themselves ignorant about a worldwide flood. If there is then evidence of the Great Flood, then that is ultimate proof of God. If there is a God then there is one to which we are accountable.
There is evidence of a worldwide flood, so much evidence that evolutionist will try to place that flood about 4 billion years ago, when really it was about 4500 years ago. If there was water 4 billion years ago the evolution must be true and God a lie. For this they are willingly ignorant.
