Faith in the Midst of Doubt and Uncertainty
Faith, in its biblical sense, is a persuasion of the mind that a statement is true, fundamentally rooted in trust [5]. It is described as the confidence in things hoped for and the conviction of matters not seen [3]. This trust is not a passive assent but a "working reality" that manifests in actions [9]. The concept of faith is closely linked to hope, which is often placed in God, Christ, God's promises, and His mercy [7].
The Bible presents faith as something that can vary in degree, ranging up to a "full assurance of faith," which leaves no room for doubt [4, 5]. This full assurance is an unwavering conviction in the truth of Scripture's declarations and a joyful steadfastness in understanding them [4]. Faith is also understood as a result of teaching, implying that knowledge is an essential component, sometimes even equated with faith itself [5]. However, faith distinguishes itself from mere knowledge by including assent, an active response [5].
Doubt and uncertainty are often contrasted with this concept of faith. Romans 14:23 states that "he who doubts is condemned if he eats, because it isn’t of faith; and whatever is not of faith is sin" [1]. This verse highlights the importance of acting out of conviction rather than uncertainty. While faith is presented as a firm conviction, there are moments when one's faith can be severely tested, particularly by "speculative difficulties" [10]. During such times, individuals may struggle against a "recoil from his Lord's harsh statements," and all truth might seem to be slipping away [10].
The New Testament also speaks of "mysteries" that require faith for understanding. These mysteries are truths that were once hidden but are now revealed through divine revelation [6]. Examples include the calling of the Gentiles into the Christian Church (Ephesians 1:9-10, 3:8-11) and the resurrection of the dead (1 Corinthians 15:51) [6]. The union between Christ and the Church is also described as a great mystery [2, 6]. These are doctrines that need explanation but cannot be fully grasped by finite human intellect, thus requiring faith [6].
The development of faith is often attributed to the work of the Holy Spirit and is obtained through grace, the Word of God, and the comfort of the Scriptures [7]. The gospel itself is a source of hope and faith [7]. The resurrection of Jesus serves as God's pledge that His revelation is true and worthy of acceptance, providing assurance for believers [4]. Christians are designated as "faithful," meaning they are full of faith and trustful [8]. This faithfulness extends to God's word and covenant, which are described as true and trustworthy [8].

- 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 ”

Peter seems to have added this not merely--probably not so much--as an assurance to his Lord of his heart's belief in Him, as for the purpose of fortifying himself and his faithful brethren against that recoil from his Lord's harsh statements which he was probably struggling against with difficulty at that moment.
