How doth the Spirit help us to pray?

We not knowing: What to pray for as we ought, the Spirit helps our infirmities, by enabling us to understand both for whom, and: What, and: How prayer is to be made; and by working and quickening in our hearts (although not in all persons, nor at all times, in the same measure) those apprehensions, affections, and graces which are requisite for the right performance of that duty.[1]

1. Rom. 8:26-27

   So whether we are at home or away, we make it our aim to please him. 10 For we must all appear before the judgment seat of Christ, so that each one may receive what is due for what he has done in the body, whether good or evil.

   Psa. 10:17

   O Lord, you hear the desire of the afflicted;
   you will strengthen their heart; you will incline your ear….

   Zech. 12:10

   And I will pour out on the house of David and the inhabitants of Jerusalem a spirit of grace and pleas for mercy, so that, when they look on me, on him whom they have pierced, they shall mourn for him, as one mourns for an only child, and weep bitterly over him, as one weeps over a firstborn.
