6 I do not say this as though the result of reasoning. Hear the Apostle himself saying, “He that spared not His Own Son, but delivered Him up for us all; how has He also not with Him given us all things?” Lo, covetous one, you have all things. All things that you love, despise, that you be not kept back from Christ, and hold to Him in whom you may possess all things. The Physician Himself then needing no such medicine, yet that He might encourage the sick, drank what He had no need of; addressing him as it were refusing it, and raising him up in his fear, He drank first.
“The Cup,” says He, “which I shall drink of;” “I who have nothing in Me to be cured by that Cup, am yet to drink it, that you who needest to drink it, may not disdain to drink.” Now consider, Brethren, ought the human race to be any longer sick after having received such a medicine? God has been now Humbled, and is man still proud? Let him hear, let him learn. “All things,” says He, have been delivered unto Me of My Father. If you desire all things, you shall have them with Me; if you desire the Father, by Me and in Me you shall have Him.
“No man knows the Father but the Son.” Do not despair; come to the Son. Hear what follows, “And he to whom the Son will reveal Him.” Thou said, “I am not able. You call me through a strait way; I am not able to enter in by a strait way.” “Come,” says He, “unto Me, all you that labour and are heavy laden.” Your burden is your swelling. “Come unto Me, all you that labour and are heavy laden, and I will refresh you. Take My yoke upon you, and learn of Me.”
