"I keep it there as the thorn in your flesh to humble you, to prevent you from being “perfect” in your own eyes, to protect you from pride, to remind you that you need My grace each day, that whenever the thought came to you, “who and who will never change", your old sin will sting, telling you that you too, don’t seem to ever change. Whenever you hold grudges against someone because of their sin, if you do not forgive them because they don’t deserve it, your own sin that you battle against for ages will convict you that you too, don’t deserve my forgiveness, but I forgave you anyway, for My sake."
The difference between the poet and the mathematician is that the poet tries to get his head into the heavens while the mathematician tries to get the heavens into his head.
— G.K. Chesterton
