Saving Faith

  Saving faith is a work wrought by the Spirit of God and the Word of God in a poor sinner.  The London Confession states,

Chapter 14: Of Saving Faith

1._____ The grace of faith, whereby the elect are enabled to believe to the saving of their souls, is the work of the Spirit of Christ in their hearts, and is ordinarily wrought by the ministry of the Word; by which also, and by the administration of baptism and the Lord's supper, prayer, and other means appointed of God, it is increased and strengthened. ( 2 Corinthians 4:13; Ephesians 2:8; Romans 10:14, 17; Luke 17:5; 1 Peter 2:2; Acts 20:32 )

2._____ By this faith a Christian believeth to be true whatsoever is revealed in the Word for the authority of God himself, and also apprehendeth an excellency therein above all other writings and all things in the world, as it bears forth the glory of God in his attributes, the excellency of Christ in his nature and offices, and the power and fullness of the Holy Spirit in his workings and operations: and so is enabled to cast his soul upon the truth thus believed; and also acteth differently upon that which each particular passage thereof containeth; yielding obedience to the commands, trembling at the threatenings, and embracing the promises of God for this life and that which is to come; but the principal acts of saving faith have immediate relation to Christ, accepting, receiving, and resting upon him alone for justification, sanctification, and eternal life, by virtue of the covenant of grace.
( Acts 24:14; Psalms 27:7-10; Psalms 119:72; 2 Timothy 1:12; John 14:14; Isaiah 66:2; Hebrews 11:13; John 1:12; Acts 16:31; Galatians 2:20; Acts 15:11 )

3._____ This 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.
( Hebrews 5:13, 14; Matthew 6:30; Romans 4:19, 20; 2 Peter 1:1; Ephesians 6:16; 1 John 5:4, 5; Hebrews 6:11, 12; Colossians 2:2; Hebrews 12:2 ) 

Charles H. Spurgeon stated,

If you have been truly born again you have a new and holy nature, and you are no longer moved towards sinful objects as you were before. The things that you once loved you now hate, and therefore you will not run after them. You can hardly understand it but so it is, that your thoughts and tastes are radically changed. You long for that very holiness which once it was irksome to hear of; and you loathe those vain pursuits which were once your delights. The man who puts his trust in the Lord sees the pleasures of sin in a new light.  For he sees the evil which follows them by noting the agonies which they brought upon our Lord when He bore our sins in His own body on the tree. Without faith a man says to himself, “This sin is a very pleasant thing, why should I not enjoy it? Surely I may eat this fruit, which looks so charming and is so much to be desired.” The flesh sees honey in the drink, but faith at once perceives that there is poison in the cup. Faith spies the snake in the grass and gives warning of it. Faith remembers death, judgment, the great reward, the just punishment and that dread word, eternity.

Martin Luther said,

For the gospel does not expressly demand works of our own by which we become righteous and are saved; indeed it condemns such works.  Rather the gospel demands faith in Christ: that He has overcome for us sin, death, and hell, and thus gives us righteousness, life, and salvation not through our works, but through His own works, death, and suffering, in order that we may avail ourselves of His death and victory as though we has done it ourselves.

Matthew Henry said,

We are too apt to rest in a bare profession of faith, and to think that this will save us; it is a cheap and easy religion to say, “We believe in the articles of the Christian faith;” but it is a great delusion to imagine that this is enough to bring us to heaven.
