Isaiah 43:1
1 But now thus saith the LORD that created thee, O Jacob, and he that formed thee, O Israel, Fear not: for I have redeemed thee, I have called thee by thy name; thou art mine
If you are born again and bought by the blood of the lamb, God has redeemed you. He has given you a whole new life. Know that God is the one who created and formed you. He brought you to life for a reason. He made you for a purpose. He knew you would fall and struggle in life. He knew that at times you would start struggling with faith. However, he still gave his only son for your redemption. If God loved you that much, then know that you are not worthless. Know that you are one of his redeemed and that you are a child of the one who spoke the everything into existence. Do not ever think you are a waste or that you are nothing. You are formed and call by name by the heavenly father and you are his.
