Patientia comes est sapientiae - Augustine of Hippo

Let us rejoice and give thanks. Not only are we become Christians, but we are become Christ. My brothers, do you understand the grace of God that is given us? Wonder, rejoice, for we are made Christ! If He is the Head, and we the members, then together He and we are the whole man.... This would be foolish pride on our part, were it not a gift of his bounty. But this is what He promised by the mouth of the Apostle: “You are the body of Christ, and severally His members” (1 Cor. 12:27).

I have read in Plato and Cicero sayings that are very wise and very beautiful; but I never read in either of them, "Come unto me, all ye that labor and are heavy laden."

Ecce respondeo dicenti, 'quid faciebat deus antequam faceret caelum et terram?' respondeo non illud quod quidam respondisse perhibetur, ioculariter eludens quaestionis violentiam: 'alta,' inquit, 'scrutantibus gehennas parabat.' aliud est videre, aliud ridere: haec non respondeo. libentius enim responderim, 'nescio quod nescio' quam illud unde inridetur qui alta interrogavit et laudatur qui falsa respondit.
