spockrates:
For by grace you have been saved through faith; and that not of yourselves, it is the gift of God; not as a result of works, so that no one may boast.
James 1:17 Every good endowment and every perfect gift is from above, coming down from the Father of lights with whom there is no variation or shadow due to change.
For we are His workmanship, created in Christ Jesus for good works, which God prepared beforehand so that we would walk in them.
Luke 1:48 for he has regarded the low estate of his handmaiden
through baptism we receives the Virtues of Faith hope and Charity, and other gifts,only a sparked or small proportion is given us, we by the grace of god have to practice our faith with good works and merit graces or multiply them Faith is an theological virtue , [143]By faith , man completely submits his intellect and his will to God.2 With his whole being man gives his assent to God the revealer. Sacred Scripture calls this human response to God, the author of revelation, “the obedience of faith”.

Faith is a grace
153 When St. Peter confessed that Jesus is the Christ, the Son of the living God, Jesus declared to him that this revelation did not come “from flesh and blood”, but from “my Father who is in heaven”.24
Faith is a gift of God, a supernatural virtue infused by him . "Before this faith can be exercised, man must have the grace of God to move and assist him; he must have the interior helps of the Holy Spirit, who moves the heart and converts it to God, who opens the eyes of the mind and ‘makes it easy for all to accept and believe the truth.’"25
Faith is a human act
[154] Believing is possible only by grace and the interior helps of the Holy Spirit. But it is no less true that believing is an authentically human act. Trusting in God and cleaving to the truths he has revealed is contrary neither to human freedom nor to human reason. Even in human relations it is not contrary to our dignity to believe what other persons tell us about themselves and their intentions, or to trust their promises (for example, when a man and a woman marry) to share a communion of life with one another. If this is so, still less is it contrary to our dignity to “yield by faith the full submission of. . . intellect and will to God who reveals”,26 and to share in an interior communion with him…
Hebrews 11:1 Now faith is the assurance of things hoped for, the conviction of things not seen. 2 For by it the men of old received divine approval. 3 By faith we understand that the world was created by the word of God, so that what is seen was made out of things which do not appear.
