NIV 1 Peter 1:17-21
17. Since you call on a Father who judges each man's work impartially, live your lives as strangers here in reverent fear.
18. For you know that it was not with perishable things such as silver or gold that you were redeemed from the empty way of life handed down to you from your forefathers,
19. but with the precious blood of Christ, a lamb without blemish or defect.
20. He was chosen before the creation of the world, but was revealed in these last times for your sake.
21. Through him you believe in God, who raised him from the dead and glorified him, and so your faith and hope are in God.
NIV 1 Corinthians 2:7
No, we speak of God's secret wisdom, a wisdom that has been hidden and that God destined for our glory before time began.
NIV 2 Timothy 1:8-10
8. So do not be ashamed to testify about our Lord, or ashamed of me his prisoner. But join with me in suffering for the gospel, by the power of God,
9. who has saved us and called us to a holy life--not because of anything we have done but because of his own purpose and grace. This grace was given us in Christ Jesus before the beginning of time,
10. but it has now been revealed through the appearing of our Savior, Christ Jesus, who has destroyed death and has brought life and immortality to light through the gospel.
NIV Titus 1:1-4
1. Paul, a servant of God and an apostle of Jesus Christ for the faith of God's elect and the knowledge of the truth that leads to godliness--
2. a faith and knowledge resting on the hope of eternal life, which God, who does not lie, promised before the beginning of time,
3. and at his appointed season he brought his word to light through the preaching entrusted to me by the command of God our Savior,
4. To Titus, my true son in our common faith: Grace and peace from God the Father and Christ Jesus our Savior.
Difficult to say.
"Timeless" might be the best answer.
No time as WE know it. Time is just God's way of keeping everything from happening at once. But HE existed out of time - before time. Everything in our universe had a beginning ('promised before the beginning of time'), and everything He created was good.
Genesis 5:1.............
This is the book of the generations of Adam. In the day that God created man, in the likeness of God made he him;
As I read it, according to the Bible (KJV), time started in the 6th day and the generations of man began with Adam!
This was after some of the other "days" of Creation! The other "days" may have been of similar duration, or they may have been longer or shorter even.
