This faith [saving faith], although it be different in degrees, and may be weak or strong, yet it is in the least degree of it different in the kind or nature of it, as is all other saving grace, from the faith and common grace of temporary believers; and therefore, though it may be many times assailed and weakened, yet it gets the victory, growing up in many to the attainment of a full assurance through Christ, who is both the author and finisher of our faith.- Philadelphia Confession of Faith, Chapter 14, Section 3
(Heb. 5:13, 14; Matt. 6:30; Rom. 4:19, 20; 2 Pet. 1:1; Eph. 6:16; 1 John 5:4, 5; Heb. 6:11, 12; Col. 2:2; Heb. 12:2)
Although temporary believers, and other unregenerate men, may vainly deceive themselves with false hopes and carnal presumptions of being in the favour of God and state of salvation, which hope of theirs shall perish; yet such as truly believe in the Lord Jesus, and love him in sincerity, endeavouring to walk in all good conscience before him, may in this life be certainly assured that they are in the state of grace, and may rejoice in the hope of the glory of God, which hope shall never make them ashamed.- Philadelphia Confession of Faith, Chapter 18, Section 1
(Job 8:13, 14; Matt. 7:22, 23; 1 John 2:3, 3:14, 18, 19, 21, 24, 5:13; Rom. 5:2, 5)
Q.119. What is temporary faith?- Philadelphia Baptist Catechism, Q/A 119-20
A. Those who for a short time take joy in certain portions of the Word of God, believing certain promises belong to them.

Q.120. Where does temporary faith fall short of saving faith?
A. Temporary believers have not the Spirit of Christ dwelling in them.
