Prayer
Lord, teach us how to pray aright,
With reverence and with fear;
Though dust and ashes in Thy sight,
We may, we must draw near.
We perish if we cease from prayer;
O grant us power to pray;
And when to meet Thee we prepare,
Lord, meet us by the way.
Westminster Confession
Chapter XXI — Of Religious Worship and the Sabbath-day.
3. Prayer with thanksgiving, being one special part of religious worship, is by God required of all men; and that it may be accepted, it is to be made in the name of the Son, by the help of his Holy Spirit, according to his will, with understanding, reverence, humility, fervency, faith, love, and perseverance; and, if vocal, in a known tongue.
4. Prayer is to be made for things lawful, and for all sorts of men living, or that shall live hereafter; but not for the dead, nor for those of whom it may be known that they have sinned the sin unto death.
