“Since our first conscious decision really to follow the teaching of Christ, we have no doubt made good progress along the way of faithfulness to his word. And yet isn’t it true that there is still much to be done? Isn’t it true, particularly, that there is still so much pride in us? We need, most probably, to change again, to be more loyal and humble, so that we become less selfish and let Christ grow in us, for “He must become more and more, I must become less and less.(…)

Conversion is the task of a moment; sanctification is the work of a lifetime. The divine seed of charity, which God has sown in our souls, wants to grow, to express itself in action, to yield results which continually coincide with what God wants. Therefore, we must be ready to begin again, to find again — in new situations — the light and the stimulus of our first conversion.
And that is why we must prepare with a deep examination of conscience, asking our Lord for his help, so that we’ll know him and ourselves better. If we want to be converted again, there’s no other way.”

St. Josemaria Escriva, Homily given on 2 March 1952, the first Sunday of Lent
