"And what of ourselves? With all these witnesses to faith around us like a cloud, we must throw off every encumbrance, every sin to which we cling, and run with resolution the race for which we are entered, our eyes fixed on Jesus, on whom faith depends from start to finish: Jesus who, for the sake of the joy that lay ahead of him, endured the torture stake, making light of its disgrace, and has taken his seat at the right hand of the throne of God. Think of him who submitted to such opposition from sinners: that will help you not to lose heart and grow faint." (Heb 12:1-3 NEB).
'Discouragement is an inclination to give up all attempts after the devout life, in consequence of the difficulties by which it is beset, and our already numerous failures in it. We lose heart; and partly in ill-temper, partly in real doubt of our own ability to persevere, we first grow querulous and peevish with God, and then relax in our efforts to mortify ourselves and to please Him. It is a sort of shadow of despair, and will lead us into numberless venial sins the first half-hour we give way to it.' (F. W. Faber).
"For all the things that were written aforetime were written for our instruction, that through our endurance and through the comfort from the Scriptures we might have hope. Now may the God who supplies endurance and comfort grant you to have among yourselves the same mental attitude that Christ Jesus had, that with one accord you may with one mouth glorify the God and Father of our Lord Jesus Christ." (Rom 15:4-6).
'Never let us be discouraged with ourselves; it is not when we are conscious of our faults that we are the most wicked; on the contrary, we are less so. We see by a brighter light; and let us remember, for our consolation, that we never perceive our sins till we begin to cure them. (Fénelon).
