"Before I formed you in the womb I knew you; Before you were born I sanctified you; I ordained you a prophet to the nations."
Your parents may have not planned you, but God did. He wanted you alive and created you for a purpose. Focusing on yourself will never reveal your purpose. You were made by God and for God, and until you understand that, life will never make sense. Only in God do we discover our origin, our identity, our meaning, our purpose, our significance, and our destiny.
But the very hairs of your head are all numbered.
