We are not justified BEFORE we believe. That is total nonsense. Please see Romans chapter 4.
A. WHAT IS JUSTIFICATION?
Strong's Concordance
dikaioó: to show to be righteous, declare righteous
Original Word: δικαιόω
Part of Speech: Verb
Transliteration: dikaioó
Phonetic Spelling: (dik-ah-yo'-o)
Definition: to show to be righteous,
declare righteous
Usage: I make righteous, defend the cause of, plead for the righteousness (innocence) of, acquit, justify; hence: I regard as righteous.
Thayer's Greek Lexicon clarifies this further:
1. properly, (according to the analogy of other verbs ending in , as τυφλόω, δουλόω) to make δίκαιος;
to render righteous or such as he ought to be
3. τινα, to declare,
pronounce, one to be just, righteous, or such as he ought to be
3 a. with the negative idea predominant,
to declare guiltless one accused or who may be accused, acquitted of a charge or reproach
3 b. with the positive idea predominant,
to judge, declare, pronounce, righteous and therefore acceptable
So justification = to be declared or pronounced to be righteous.
B. WHO IS THE ONE WHO JUSTIFIES?
It is God Himself -- Almighty God -- who justifies purely by His grace.
C. WHO IS THE ONE WHO IS JUSTIFIED?
It is the vilest of sinners who repents and believes on the Lord Jesus Christ, e.g. the criminal on the cross, and Saul the persecutor of Christians
D. ON WHAT GROUNDS CAN GOD BE JUST AND THE JUSTIFIER OF THE UNGODLY?
On the sole basis of the finished work of Christ -- His sacrificial death, His burial, and His resurrection.
E. WHY IS JUSTIFICATION APART FROM WORKS?
Because it is purely by the grace of God that any sinner may be justified.
F. HOW DO WE KNOW THIS IS TRUE?
The fourth chapter of the epistle to the Romans lays it all out in black and white.
G. ARE WE THEN SAVED (JUSTIFIED) UNTO GOOD WORKS?
Absolutely. But the works DO NOT justify us. See
Ephesians 2:8-10
To understand justification by grace through faith we must enter the Divine Courtroom of God, with God presiding as the absolutely righteous Judge. When we stand before Him, how do we plead? "GUILTY". All of us are guilty of violating one, or more, or all, of God's commandments. What is the just penalty for our guilt? It is death -- both the first and second deaths. But God does not desire to see anyone in Hell (the Lake of Fire created for the devil and his angels).
Therefore Christ paid the full penalty for our sins on the cross, and rose again FOR OUR JUSTIFICATION. But how do we appropriate this opportunity to be justified? By obedience to the Gospel, which is repentance toward God and faith towards our Lord Jesus Christ. So the moment a sinner calls upon the Lord to be saved (
Romans 10) he or she is justified -- declared righteous and at the same time declared "NOT GUILTY". This has absolutely nothing to do with the future good works God expects from His children.
