However perfect anyone may be, yet he may fall into temptations, and perhaps into such as may be useful. Nor is it wonderful that man should never be exempt from them, because he always hath in himself their source; scarce are we delivered from one temptation when another attacks us. Such is the lot of the posterity of Adam, that they should always have something to suffer, because they have forfeited their primitive happiness. We vainly flatter ourselves that we shall conquer temptations by flying; if we join not patience and humility we shall torment ourselves to no purpose. We shall more certainly compass our end by imploring God's assistance than by using any means of our own.

Be constant, Heloise, and trust in God; then you shall fall into few temptations: when they come stifle them at their birth--let them not take root in your heart. ‘Apply remedies to a disease,’ said an ancient, ‘at the beginning, for when it hath gained strength medicines are of no avail’: temptations have their degrees, they are at first mere thoughts and do not appear dangerous; the imagination receives them without any fears; the pleasure grows; we dwell upon it, and at last we yield to it.

The love letters of Abelard and Heloise — Part 38

Do you now, Heloise, applaud my design of making you walk in the steps of the saints? Do my words give you any relish for penitence? Have you not remorse for your wanderings, and do you not wish you could, like Magdalen, wash our Saviour's feet with your tears? If you have not yet these ardent aspirations, pray that you may be inspired by them. I shall never cease to recommend you in my prayers and to beseech God to assist you in your design of dying holily. You have quitted the world, and what object was worthy to detain you there? Lift up your eyes always to Him to whom the rest of your days are consecrated. Life upon this earth is misery; the very necessities to which our bodies are subject here are matters of affliction to a saint. ‘Lord,’ said the royal prophet, ‘deliver me from my necessities.’ Many are wretched who do not know they are; and yet they are more wretched who know their misery and yet cannot hate the corruption of the age. What fools are men to engage themselves to earthly things! They will be undeceived one day, and will know too late how much they have been to blame in loving such false good. Truly pious persons are not thus mistaken; they are freed from all sensual pleasures and raise their desires to Heaven.
