Here is a prayer from that collection of Puritan prayers known as The Valley of Vision. This is a prayer of confidence–confidence in the greatness and the grace of God. It is a bold prayer made through a right apprehension of the character of God.
O God, Thou art very great,
My lot is to approach thee with godly fear and humble confidence,
for thy condescension equals thy grandeur,
and thy goodness is thy glory.
I am unworthy, but thou dost welcome;
guilty, but thou art merciful;
poor, but thy riches are unsearchable.
Thou hast shown boundless compassion towards me
by not sparing thy son,
and by giving me freely all things in him;
This is the foundation of my hope,
the refuge of my safety,
the new and livnig way to thee,
the means of that conviction of sin,
brokenness of heart, and self-despair,
which will endear me to the gospel.
Happy are they who are Christ’s
in him at peace with thee,
justified from all things,
delivered from coming wrath,
made heirs of future glory;
Give me such deadness to the world,
such love to the Saviour,
such attachment to his house,
such devotedness to his service,
as proves me a subject of his salvation.
May every part of my character and conduct
make a serious and amiable impression on others,
and impel them to ask the way to the Master.
Let no incident of life, pleasing or painful,
injure the prosperity of my soul,
but rather increase it.
Send me thy help,
for thine appointments are not meant
to make me independent of thee,
and the best means will be vain
without super-added blessings.
