Excerpt from Grace Abounding to the Chief of Sinners: Or Brief Faithful Relation Exceeding Mercy God Christ his Poor Servant John (Penguin Classics):

I will now (God willing), before I proceed any farther, give you in a word or two, what, as I conceive, was the cause of this temptation; and also after that, what advantage, at the last, it became unto my soul. 237. For the causes, I conceived they were principally two: of which two also I was deeply convinced all the time this trouble lay upon me. The first was, for that I did not, when I was delivered from the temptation that went before, still pray to God to to keep me from the temptations that were to come; for though, as I can say in truth, my soul was much in prayer before this trial seized me, yet then I prayed only, or at the most principally, for the removal of present troubles, and for fresh discoveries of His love in Christ, which I saw afterwards was not enough to do; I also should have prayed that the great God would keep me from the evil that was to come. 238. Of this I was made deeply sensible by the prayer of holy David, who when he was under present mercy, yet prayed that God would hold him back from sin and temptation to come; Then, saith he, shall I be upright, and I shall be innocent from the great transgression. Psalm xix. 13. By this very word was I galled and condemned quite through this long temptation. 239. That was also another word that did much condemn me for my folly, in the neglect of this duty. Heb. iv. 16: Let us therefore come boldly unto the throne of grace, that we may obtain mercy, and find grace to help in time of need. This I had not done, and therefore was thus suffered to sin and fall, according to what is written, Pray that ye enter not into temptation. And truly this very thing is to this day of such weight and awe upon me, that I dare not, when I come before the Lord, go of my knees, until I intreat Him for help and mercy against the temptations that are to come; and I do beseech thee, reader, that thou learn to beware of my negligence, by the afflictions, that for this thing I did for days, and months, and years, with sorrow undergo.

I was deeply convicted by this passage, for I know I do not pray as often as I should. Many times, I pray "when I need to" or when I face times of desperation. But I know I need to go to God continually, not just when I am making a request.

Lord, please make me a prayer warrior.
