Pink offers us so much wisdom in the area of prayer. Let's look again at some thoughts on prayer from chapter 3 of his A Guide to Fervent Prayer:
Herein, indeed, is a humbling truth, yet a fact it is that Christians are, in themselves, incapable of discharging their duty. Though the love of God has been shed abroad in their hearts and a principle of holiness (or new nature) communicated to them, yet they are unable to perform the good they ardently desire to do. Not only are they still very ignorant of many of the requirements of God's revealed will, but indwelling sin ever opposes and seeks to incline their hearts in a contrary direction. Thus it is imperative that they daily seek from God fresh supplies of grace. Though assured that God shall surely complete His good work in us (Phil. 1:6), that does not render needless our crying to Him “that performeth all things for me [us]” (Ps. 57:2, brackets mine). Nor does the privilege of prayer release us from the obligation of obedience. Rather, in prayer we are to beg Him to quicken us to the performance of those duties He requires. The blessing of access to God is not designed to discharge us from the regular and diligent use of all the means God has appointed for our practical sanctification, but is meant to provide for our seeking of the Divine blessing on our use of all the means of grace. Our duty is this: to ask God to work in us “both to will and to do of his good pleasure” (Phil. 2:13); to avoid quenching His Spirit by slothfulness and disobedience, especially after we have prayed for His sweet influences (I Thess. 5:19); and to use the grace He has already given us.
