Leo Tolstoy said this quote

Not in order to justify, but simply in order to explain my lack of consistency, I say: Look at my present life and then at my former life, and you will see that I do attempt to carry them out. It is true that I have not fulfilled one thousandth part of them [Christian precepts], and I am ashamed of this, but I have failed to fulfill them not because I did not wish to, but because I was unable to. Teach me how to escape from the net of temptations that surrounds me, help me and I will fulfill them; even without help I wish and hope to fulfill them.Attack me, I do this myself, but attack me rather than the path I follow and which I point out to anyone who asks me where I think it lies. If I know the way home and am walking along it drunkenly, is it any less the right way because I am staggering from side to side! If it is not the right way, then show me another way; but if I stagger and lose the way, you must help me, you must keep me on the true path, just as I am ready to support you. Do not mislead me, do not be glad that I have got lost, do not shout out joyfully: “Look at him! He said he was going home, but there he is crawling into a bog!” No, do not gloat, but give me your help and support.
