Your eyes saw my unformed substance; in your book were written, every one of them, the days that were formed for me, when as yet there was none of them. [ESV] Psalm 139:16
During the embryogenesis of you, as your cells divided and replicated to form a ball that later became an embryo that became a foetus that became you, God was there watching, writing out how every day of your life would be even before you were born / lived them. Yes life happened and at worst became so chaotic, that it made you wonder, if indeed God had pre-planned a life of wonderfully fulfilled purposes for you, what happened? The fact that you know now, that the chaotic mess you’ve found yourself in wasn’t in the original plan of the good life that was pre-planned for you by God; you can turn the turmoil to your advantage. Since you know you were not created and purposed to live a life of pain, shame, ruin and disgrace, but a successful life, then don’t let anyone keep beating you down with barrages of negativity. You are not a nonentity, nor are you worthless or useless. Now go and get your life back! You were created for greatness, not mediocrity or ordinariness. Ask the Lord Jesus to help you retrace your steps back to the path He predestined before you were formed to live and He will. Live it well to His glory!
