'Day' in the Bible

So we have the prophetic word strongly confirmed. You will do well to pay attention to it, as to a lamp shining in a dismal place, until the day dawns and the morning star rises in your hearts.

(for as he lived among them, that righteous man tormented himself day by day with the lawless deeds he saw and heard)—

then the Lord knows how to rescue the godly from trials and to keep the unrighteous under punishment until the day of judgment,

But by the same word, the present heavens and earth are stored up for fire, being kept until the day of judgment and destruction of ungodly men.

Dear friends, don’t let this one thing escape you: With the Lord one day is like a thousand years, and a thousand years like one day.

But the Day of the Lord will come like a thief; on that day the heavens will pass away with a loud noise, the elements will burn and be dissolved, and the earth and the works on it will be disclosed.

as you wait for and earnestly desire the coming of the day of God. The heavens will be on fire and be dissolved because of it, and the elements will melt with the heat.

But grow in the grace and knowledge of our Lord and Savior Jesus Christ. To Him be the glory both now and to the day of eternity. Amen.
