Brother Lawrence said this quote

We should fix ourselves firmly in the presence of God by conversing all the time with Him...we should feed our soul with a lofty conception of God and from that derive great joy in being his. We should put life in our faith. We should give ourselves utterly to God in pure abandonment, in temporal and spiritual matters alike, and find contentment in the doing of His will,whether he takes us through sufferings or consolations.

I regard myself as the most wretched of all men, stinking and covered with sores, and as one who has committed all sorts of crimes against his King. Overcome by remorse, I confess all my wickedness to Him, ask His pardon and abandon myself entirely to Him to do with as He will. But this King, filled with goodness and mercy, far from chastising me, lovingly embraces me, makes me eat at His table, serves me with His own hands, gives me the keys of His treasures and treats me as His favorite. He talks with me and is delighted with me in a thousand and one ways; He forgives me and relieves me of my principle bad habits without talking about them; I beg Him to make me according to His heart and always the more weak and despicable I see myself to be, the more beloved I am of God.

He does not ask much of us, merely a thought of Him from time to time, a little act of adoration, sometimes to ask for His grace, sometimes to offer Him your sufferings, at other times to thank Him for the graces, past and present, He has bestowed on you, in the midst of your troubles to take solace in Him as often as you can. Lift up your heart to Him during your meals and in company; the least little remembrance will always be the most pleasing to Him. One need not cry out very loudly; He is nearer to us than we think.

When the mind, for want of being sufficiently reduced by recollection at our first engaging in devotion, has contracted certain bad habits of wandering and dissipation, they are difficult to overcome, and commonly draw us, even against our wills, to the things of the earth.I believe one remedy for this is to confess our faults, and to humble ourselves before God. I do not advise you to use multiplicity of words in prayer: many words and long discourses being often the occasions of wandering. Hold yourself in prayer before God, like a dumb or paralytic beggar at a rich man's gate. Let it be your business to keep your mind in the presence of the Lord. If it sometimes wander and withdraw itself from Him, do not much disquiet yourself for that: trouble and disquiet serve rather to distract the mind than to re-collect it: the will must bring it back in tranquility. If you persevere in this manner, God will have pity on you.
