Nature of Faith in Salvation and Justification
Justification is understood as the judicial act of God by which he pardons the sins of those who believe in Christ, treating them as righteous in the eyes of the law [1]. This act is forensic, meaning it is a legal declaration rather than an internal change, and it is opposed to condemnation [1]. The law is not set aside but declared to be fulfilled in the strictest sense through Christ [1].
Faith, in this context, is generally defined as the persuasion of the mind that a statement is true, with its primary idea being trust [2]. It involves knowledge and assent, and it can range in degree up to full assurance [2, 3]. The New Testament emphasizes that "the just shall live by faith" (Romans 1:17) [6].
Different Christian traditions articulate the nature of faith in salvation and justification with varying emphases:
Protestant Traditions (Lutheran, Reformed, Methodist): These traditions generally emphasize justification by faith alone (sola fide). The Augsburg Confession states that people "are justified freely for Christ’s sake, through faith, when they believe that they are received into favor and that their sins are forgiven for Christ’s sake" [9]. Similarly, the Anglican Thirty-Nine Articles affirm that "we are accounted righteous before God, only for the merit of our Lord and Saviour Jesus Christ by Faith, and not for our own works or deservings" [10]. John Calvin, a key figure in Reformed theology, extensively discussed justification by faith [11]. This view holds that God justifies "the person by faith in Jesus" (Romans 3:26) [4]. John Gill, one theologian, highlights God's free grace as the moving cause of justification [8]. Charles Hodge, one theologian, distinguishes justification as a "forensic act" from sanctification, which is a progressive work [14]. Adam Clarke, a Methodist commentator, notes that neither the works of the Jewish law nor any other law could justify a person, making justification by faith both reasonable and necessary [7].
Catholic Tradition: The Council of Trent, while affirming the necessity of faith, also emphasizes the role of good works and sacraments in the process of justification [13]. Thomas Aquinas, a scholastic theologian, taught that grace is necessary not only to heal corrupted human nature but also to enable individuals to perform deeds meritorious of everlasting life [15].
Eastern Orthodox Tradition: The Eastern Orthodox understanding often views salvation as a lifelong process of theosis (deification), where humanity is united with God through grace, faith, and participation in the sacraments, rather than a singular forensic declaration of justification [12].
While justification is a divine act, sanctification is the work of the Holy Spirit, bringing the whole nature under the influence of new gracious principles implanted in the soul, leading to a progressive growth in holiness [5, 14].

- Easton's Bible Dictionary “Easton's Bible Dictionary: Justification — A forensic term, opposed to condemnation. As regards its nature, it is the judicial act of God, by which he pardons all the sins of those who believe in Christ, and accounts, accepts, and treats them as righteous in the eye of the law, i.e., as conformed to all its demands. In addition to the pardon (q.v.) of sin, justification declares that all the claims of the law are satisfied in respect of the justified. It is the act of a judge and not of a sovereign.

- 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 ”

The "full assurance [Gr. plerophoria, full bearing'] of faith" (Heb. 10:22) is a fulness of faith in God which leaves no room for doubt. The "full assurance of understanding" (Col. 2:2) is an entire unwavering conviction of the truth of the declarations of Scripture, a joyful steadfastness on the part of any one of conviction that he has grasped the very truth.

In other words, sanctification is the carrying on to perfection the work begun in regeneration, and it extends to the whole man (Rom. 6:13; 2 Cor. 4:6; Col. 3:10; 1 John 4:7; 1 Cor. 6:19).
