In a hadith qudsi, Allah tells us
I am as My servant thinks I am. I am with him when he makes mention of Me. If he makes mention of Me to himself, I make mention of him to Myself; and if he makes mention of Me in an assembly, I make mention of him in an assembly even better than that one. And if he takes one step towards me, I take ten steps towards him. And if he comes walking to Me, I go running towards him.
And:
God the Almighty has said, "O son of Adam, so long as you call upon Me and ask of Me, I shall forgive you for what you have done, and I shall not mind. O son of Adam, were your sins to reach the clouds of the sky and were you to ask forgiveness of Me, I would forgive you. O son of Adam, were you to come to Me with sins nearly as great as the earth and were you to face Me, ascribing no partner to Me, I would bring you forgiveness nearly as great as it."
