Bible: Time had a beginning.

Titus (1:2) a faith and knowledge resting on the hope of eternal life, which God, who does not lie, promised before the beginning of time, NIV

2 Timothy (1:9) 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, 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
