From The Valley of Vision, a book of Puritan prayers:

My God, I bless you that you have given me the eye of faith to see you as Father, to know you as a covenant God, to experience your love planted in me; for faith is the grace of union by which I spell out my entitlement to you.

Faith casts my anchor upward where I trust in you and engage you to be my Lord.

Be pleased to live and move within me, breathing in my prayers, inhabiting my praises, speaking in my words, moving in my actions, living in my life, causing me to grow in grace.

Your bounteous goodness has helped me believe, but my faith is weak and wavering, its light dim, its steps tottering, its increase slow, its backsliding frequent; it should scale the heavens, but lies groveling in the dust.

Lord, fan this divine spark into glowing flame.

When faith sleeps, my heart becomes an unclean thing, the fount of every loathsome desire, the cage of unclean lusts all fluttering to escape, the noxious tree of deadly fruit, the open wayside of earthly tares.

Lord, awake faith to put forth its strength until all heaven fills my soul and all impurity is cast out.
