Imitation of Christ

Datur etiam consolatio divina, ut homo fortior sit ad sustinendum adversa. Sequitur etiam tentatio, ne se elevet de bono. Non dormit diabolus, nec caro adhuc mortua est. Ideo non cesses te præparare ad certamen, quia a dextris et a sinistris sunt hostes qui nunquam quiescunt. 
 

Divine comfort is given that a man may be stronger to bear adversities. And temptation follows, lest he be lifted up because of the benefit. The devil sleeps not; your flesh is not yet dead; therefore, cease not to make yourself ready for the battle, for enemies stand on your right hand and on your left, and they are never at rest.

Imitation of Christ, II, 9:8
