Spiritual Salvation: Justification and Sanctification

I think the unified merit of Jesus Christ our Lord and Savior is received by grace alone through faith alone in Christ alone; that is, it is received through God's dear Son's imputed righteousness of His active and passive obedience.  Jesus' active obedience is His perfect life and His passive obedience is His perfect death.  It is a forensic or legal declaration concerning His imputed righteousness about Reformed justification.  It is not through the sacraments of Roman Catholicism or infused merit or grace.  Justification is a once and for all legal pronouncement and declaration by God through His eternally begotten Son.  I do not think infusion has a place in God's plan of spiritual salvation.  I think sanctification is all of divine and sacred grace imparted to us by faith alone through the all-virterousness of the Cross.  I think we can ask God to implant in us more faith by His Spirit through the grace of the all-sufficient Cross.   

Let us consider the words of the Reformed confession in the London Confession about Reformed justification and I will end with these words:

Chapter 11: Of Justification

1._____ Those whom God effectually calleth, he also freely justifieth, not by infusing righteousness into them, but by pardoning their sins, and by accounting and accepting their persons as righteous; not for anything wrought in them, or done by them, but for Christ's sake alone; not by imputing faith itself, the act of believing, or any other evangelical obedience to them, as their righteousness; but by imputing Christ's active obedience unto the whole law, and passive obedience in his death for their whole and sole righteousness by faith, which faith they have not of themselves; it is the gift of God.
( Romans 3:24; Romans 8:30; Romans 4:5-8; Ephesians 1:7; 1 Corinthians 1:30, 31; Romans 5:17-19; Philippians 3:8, 9; Ephesians 2:8-10; John 1:12; Romans 5:17 ) 2._____ Faith thus receiving and resting on Christ and his righteousness, is the alone instrument of justification; yet it is not alone in the person justified, but is ever accompanied with all other saving graces, and is no dead faith, but worketh by love.
( Romans 3:28; Galatians 5:6; James 2:17, 22, 26 )
3._____ Christ, by his obedience and death, did fully discharge the debt of all those that are justified; and did, by the sacrifice of himself in the blood of his cross, undergoing in their stead the penalty due unto them, make a proper, real, and full satisfaction to God's justice in their behalf; yet, inasmuch as he was given by the Father for them, and his obedience and satisfaction accepted in their stead, and both freely, not for anything in them, their justification is only of free grace, that both the exact justice and rich grace of God might be glorified in the justification of sinners.
( Hebrews 10:14; 1 Peter 1:18, 19; Isaiah 53:5, 6; Romans 8:32; 2 Corinthians 5:21; Romans 3:26; Ephesians 1:6,7; Ephesians 2:7 )
4._____ God did from all eternity decree to justify all the elect, and Christ did in the fullness of time die for their sins, and rise again for their justification; nevertheless, they are not justified personally, until the Holy Spirit doth in time due actually apply Christ unto them.
( Galatians 3:8; 1 Peter 1:2; 1 Timothy 2:6; Romans 4:25; Colossians 1:21,22; Titus 3:4-7 )
5._____ God doth continue to forgive the sins of those that are justified, and although they can never fall from the state of justification, yet they may, by their sins, fall under God's fatherly displeasure; and in that condition they have not usually the light of his countenance restored unto them, until they humble themselves, confess their sins, beg pardon, and renew their faith and repentance.
( Matthew 6:12; 1 John 1:7, 9; John 10:28; Psalms 89:31-33; Psalms 32:5; Psalms 51; Matthew 26:75 )
6._____ The justification of believers under the Old Testament was, in all these respects, one and the same with the justification of believers under the New Testament.
( Galatians 3:9; Romans 4:22-24 )
