If we don't pray according to the needs of the heart, we repress our deepest longings. Our prayers may not be rational, and we may be quite aware of that, but if we repress our needs, then those unsaid prayers will fester.
Prayer is first and foremost an act of love
A heart-felt prayer is not recitation with the lips. It is a yearning from within which expresses itself in every word, every act, nay every thought of people.
What signifies the sound of words in prayer without the affection of the heart, and a sedulous application of the proper means that may naturally lead us to such an end?
Prayer is not eloquence but earnestness.
...True prayer is measured by weight, not by length. A single groan before God may have more fullness of prayer in it than a fine oration of great length.
Kingdom praying and its efficacy is entirely a matter of the innermost heart's being totally open and honest before God. It is a matter of what we are saying with our whole being, moving with resolute intent and clarity of mind into the flow of God's action.
I do not know What kind of my obedience I should tender. More than my all is nothing; nor my prayers Are not words holy hallowed, nor my wishes More worth than empty vanities; yet prayers and wishes Are all I can return.
Watch your motive before God; have no other motive in prayer than to know Him.
It is the burning lava of the soul that has a furnace within--a very volcano of grief and sorrow-it is that burning lava of prayer that finds its way to God. No prayer ever reaches God's heart which does not come from our hearts.
The custom of speaking to God Almighty as freely as with a slave - caring nothing whether the words are suitable or not, but simply saying the first thing that comes to mind from being learnt by rote by frequent repetition - cannot be called prayer: God grant that no Christian may address Him in this manner.
He prays best who, not asking God to do man's work, prays penitence, prays resolutions, and then prays deeds--thus supplicating with heart and head and hands.
May our prayers today, and every day, be from our hearts and with the focus of our whole being.
