Lectures on Faith
“Are you not dependent on your faith, or belief, for the acquisition of all knowledge, wisdom and intelligence?” (1:11).
“And as faith is the moving cause of all action in temporal concerns, so it is in spiritual; for the Savior has said, and that truly, that ‘He that believeth and is baptized, shall be saved.’ (Mark 16:16)” (1:12).
“But those who have not made this sacrifice to God, do not know that the course which they pursue is well pleasing in his sight; for whatever may be their belief or their opinion, it is a matter of doubt and uncertainty in their mind; and where doubt and uncertainty is, there faith is not, nor can it be. For doubt and faith do not exist in the same person at the same time. So that persons whose minds are under doubts and fears cannot have unshaken confidence, and where unshaken confidence is not, there faith is weak, and where faith is weak, the persons will not be able to contend against all the opposition, tribulations and afflications which they will have to encounter in order to be heirs of God, and joint heirs with Christ Jesus; and they will grow weary in their minds, and the adversary will have power over them and destroy them” (6:12). Although the first 2 sentences could seem to imply that belief is in the domain of doubt, which is not of faith, the third sentence could be taken to imply that belief is a “weak” form of faith.
“. . . there is a great difference between believing in God and knowing him: knowledge implies more than faith” (7:16).
