Solus Christus
Take therefore first, as an indestructible foundation, the Cross, and build upon it the other articles of the faith.
God is a great lover of man. He did not hesitate to surrender His Son as prey in order to spare His servant. He surrendered His only-begotten to purchase hard-hearted servants. He paid the blood of His Son as the price. O the philanthropy of the Master! And do not tell me again, "I sinned a lot; how can I be saved?" You cannot save yourself, but your Master can, and to such a great degree as to obliterate your sins. Pay attention very carefully to the discourse. He wipes out the sins so completely that not a single trace of them remains.
"Christ is Master by virtue of His own essence and Master by virtue of His incarnate life. For He creates man from nothing, and through His own blood redeems him when dead in sin; and to those who believe in Him He has given His grace. When Scripture says, 'He will reward every man according to his works' (Matt 16:27), do not imagine that works in themselves merit either hell or the kingdom. On the contrary, Christ rewards each man according to whether his works are done with faith or without faith in Himself; and He is not a dealer bound by contract, but our Creator and Redeemer."
