a long sentence

It took me a few minutes to dissect it and then put together in order to fully understand what it means.

"The fact that it is possible for anyone to say of those who claim to seek holiness that the profession has not been accompanied with increasing humility, is a loud call to all earnest Christians, whatever truth there be in the charge, to prove that meekness and lowliness of heart are the chief marks by which they who follow the Lamb of God are to be known."
