A very good question, Fair Heavens. Scripture is the history of how God deals with man, and that history has a beginning, even if God does not. Genesis tells us how the creative power of God worked in the beginning of our world. John 1 tells us that our God, the one who spoke the powerful word which created this world, entered the same world and combined his divinity with our humanity in order to save all those who believe in Him, and give us back the eternal life man had in the beginning.
So there is a new beginning for every human being who hears His Word, and accepts it by faith. When you thank Him in your sincere prayer for this gift, it is yours, and he gives you the faith you need, and willingness to let Him guide you into His truth as a Christian, as His child, redeemed from sin to live a completely new life. That is your new beginnng.
