Anytime you feel condemned or unworthy of God, remember you didn’t call yourself. You were minding your business in oblivious nothingness when someone chose to create you.
He chose to make you his child. He chose to give you an inheritance in him and to bring you into his fold. He chose to give you a purpose and a future. It’s all on him.
If he wants you, he will sustain you and provide grace to live for him. No worries.
