Some Cayce quotes to get you started:
Hence, as has been termed by many, that FAITH - PURE faith - accepting or rejecting without basis of reason, or BEYOND the ken or scope of that as is perceived through that that man brings to his own activity through that of his five senses ... In the concepts then, as individuals in the group, in the first portion of this lesson let each so examine themselves in the light of that they have attained with the concept of their individual ideal, and we will find upon what faith is founded in THEIR experience. (262-14)
(Q) How can I so strengthen my faith so as to become a fitting channel of help in God's healing of my daughter, [275]?
(A) Magnify in the words of mouth, the acts of the body and hand, that as is GIVEN day by day. As the ideal is a growth, as the activities of the physical and mental consciousness through confidence brings that seeking of the mental and material body to awaken to the spiritual activities, so may the GROWTH in faith BRING the activating forces of the spirit that makes alive in the flesh. (262-14)
(Q) What is the comparative extent of my faith, and how may I extend and use it to achieve the most benefit?
(A) Just as given, faith is the essence of creative forces within the active force of that of an individual to which they apply themselves in the spiritual activity of their experience. So, in the application of that known to self as an expression of that faith as is manifest in every child of God - that in its active force puts that known into operation - does this grow, expand, or BECOME the basis OF the activities of self in those directions as necessary. (262-17)
... for without faith none may gain the highest development in the material or the spiritual plane; for when one may not have faith in that not seen, how may one expect that reflected from self to inspire others to faith in that the body-mind, the mental-mind, or the self represents? (369-3)
... faith is the essence of creative forces within the active force of that of an individual to which they apply themselves in the spiritual activity of their experience. So, in the application of that known to self as an expression of that faith as is manifest in every child of God - that in its active force puts that known into operation - does this grow, expand, or BECOME the basis OF the activities of self in those directions as necessary. (262-17)
To be sure, there must be faith irrespective of works, but faith without works is dead, or it bears little relationship. For, activity of spirit in the earth is not a latent but a very positive fact ... (3361-1)
As each have their own concept of faith, as to whether this is grounded in experience in relationship to life's activities in the material, or to the activities in the mental, depends much upon what has been held as the ideal of that individual. (262-14)
(Q) Could the entity receive a message at this time that her faith may be strengthened?
(A) Add unto thy faith works, that showeth forth those attributes that are expressions of His Spirit in the world. So shall it, the faith, become the evidence of things not seen, and His grace, His mercies, will abide with you whithersoever thou goest. (262-15)
(Q) Are my attempts at meditation accomplishing anything outside myself?
(A) These are but questionings of self, and questionings of the promises as are given! Might be termed lack of faith in self or the promise, for each thought, each atom, has its own weight as is expended in whatever direction it MAY be guided by the thought of self! To be sure, it ACCOMPLISHES, then, that in self and that outside of self. He that doubteth, then - doubteth self, doubteth Him! (262-17)
(Q) How can I strengthen my faith?
(A) Put that thou hast to the test in thine self. Know that, as it is used, it grows. (262-17)
Keep to those purposes, those attitudes of helpful hopefulness; that the opportunities accorded may be used in service to others. Such an attitude kept in the mental forces will bring the renewing of the faith in the divine, which is the heritage of every soul. (849-25)
For as the man thinketh in his heart, so is he. Then, if ye would not be condemned, condemn not. If ye would have faith, SHOW faith. If ye would have love, show love. (254-101)
Let the shadow pass. Look to the hope that springs anew, that has prompted thee to arise and go to them in His name. Be thou strong in the might of thy Lord. Be thou ready not as sacrifice, but as He has given, His pleasure rather is in service unto thy fellow man. Thus may the paths be made straight. Thus may those toils, those troubles, those conditions that have upset thee mentally, bring again the pure flowing spiritual aid into thy soul, thy body, thy mind. Keep those things near and dear. Let those sentiments that are often called of the mind grow deeper, for a PURPOSE - that thou mayest fulfill thy purpose in Him. Let Him have His way. Let Him guide thee. Keep the faith - keep the faith - keep the faith! (378-26)
In the abilities, keep in the way in which ye judge not, if ye would not be judged. Remember, with what measure ye mete to others must eventually be meted to thee. If ye would have friends, if ye would have love, if ye would have patience, manifest same. Each of these are the attributes of the spirit of truth and as ye apply same in thy experience, the greater becomes thy measure of faith. For if ye have not faith in others, how can ye have faith in God? If ye have not faith in God, how can ye find it in thyself? (5079-1)
To have faith in God one must know of Him and talk with Him often. One must walk with Him in the night, yea in the light, yea in all manner of places. Remember, His hand may guide thee. (3234-1)
For if ye would have faith, show it! If ye would have friends, be friendly! (1522-1)
Do not lose faith in SELF, for if faith is lost in self and self's abilities to accomplish, then there is already defeat staring thee in the face! This would be true for every individual. Becoming discouraged only lessens the capacities of individuals to become aware of that consciousness of the divine forces and divine rights that may be sought by each individual ... (257-131)
He who doubts that the best will come to him with doing of that which is correct is already defeated. Don't blame others for what has happened or may happen. Do right yourself, physically, mentally and spiritually, and the best will come to you. (5203-1)
"For all that ye may ever keep is just what you give away, and that you give away is advice, counsel, manner of life you live yourself." The manner in which you treat your fellow man, your patience, your brotherly love, your kindness, your gentleness. That you give away, that is all that ye may possess in those other realms of consciousness. (5259-1)
