Faith as the Source of Spiritual Life in Christianity
Scripture identifies faith as the instrument through which believers receive and maintain spiritual life. Paul declares in Romans 1:17 that "the righteous shall live by faith" [4], establishing faith not merely as intellectual assent but as the animating principle of Christian existence. This life originates in God's favor, which is "the source of spiritual life" [6], and flows through Christ, who is himself "the true God, and eternal life" [8].
Faith as Trust and Assent
Faith involves both persuasion and trust—"the persuasion of the mind that a certain statement is true," yet its "primary idea is trust" [1]. This dual character distinguishes faith from mere knowledge: while knowledge is "an essential element in all faith" [1], faith includes assent and reliance. one commentary tradition on 1 Thessalonians describes this as "the working reality of your faith," not "an otiose assent" but "a realizing, working faith" that manifests in continuous action [9]. Faith thus becomes the conduit through which divine life enters human experience.
The Trinitarian Source
Spiritual life has a Trinitarian origin. God the Father is its author [2], Christ mediates it [2, 5], and the Holy Spirit imparts it [2]. Romans 8:2 speaks of "the law of the Spirit of life in Christ Jesus" [7], locating spiritual vitality in the believer's union with Christ through the Spirit's work. This life "is maintained by Christ" and specifically by "faith" [2], alongside the Word of God and prayer. One commentary notes that "having Christ make his home in your hearts is the source of spiritual power for life and ministry" [10], echoing the Johannine emphasis on abiding in Christ.
Faith's Developmental Character
Spiritual life "has its origin in the new-birth" and "has its infancy" [2], indicating that faith initiates a process rather than completing it. Faith admits of "many degrees up to full assurance of faith, in accordance with the evidence on which it rests" [1], and is "the result of teaching" [1]. The believer's faith grows through engagement with Scripture, which is "the instrument" of spiritual life [2], and through the Spirit's ongoing work, who is identified as the author of hope "through grace" and "the word" [3].
This framework positions faith not as one virtue among others but as the essential means by which the Christian receives, sustains, and develops the life that originates in God's favor and flows through Christ by the Spirit.

- Easton's Bible Dictionary “Easton's Bible Dictionary: Faith — Faith is in general the persuasion of the mind that a certain statement is true (Phil. 1:27; 2 Thess. 2:13). Its primary idea is trust. A thing is true, and therefore worthy of trust. It admits of many degrees up to full assurance of faith, in accordance with the evidence on which it rests. Faith is the result of teaching (Rom. 10:14-17). Knowledge is an essential element in all faith, and is sometimes spoken of as an equivalent to faith (John 10:38; 1 John 2:3). Yet the two are distinguished in this respect, that faith includes in it assent, which is an act ”
