As for myself, I can truly say that Jesus Christ and Him crucified is the sum of all knowledge to me. He is the highest intellectualism! He is the grandest philosophy to which my mind can attain! He is the pinnacle that rises loftier than my highest aspirations and deeper than this great Truth of God I wish never to fathom! Jesus Christ and Him crucified is the sum total of all I want to know and of all the Doctrines which I profess and preach!
– Charles Spurgeon –
from his sermon: Christ Crucified
