Without truth there is no regeneration; for it is by “the word of truth” that we are begotten and born again. (James 1:18; 1 Peter 1:23)
Without truth there is no justification; for we are justified by faith, which faith consists in crediting God’s truth, and so, gives peace with God. (Romans 4:20-24; Romans 5:1)
Without the truth there is no sanctification; for the Lord Jesus Himself says, “Sanctify them through thy truth: thy word is truth.” (John 17:17)
And without the truth there is no salvation; for “God hath from the beginning chosen you to salvation through sanctification of the Spirit and belief of the truth.” (2nd Thessslonians 2:13)
And as the truth is the instrumental cause of all these blessings, the divinely appointed means whereby they become manifested mercies, so truth enters into and is received by all the graces of the Spirit as they come forth into living exercise. Thus, without the truth, there is no faith; for the work of faith is to believe the truth.
What is all the difference between faith and delusion?
That faith believes God’s truth, and delusion credits Satan’s lies. “And for this cause God shall send them strong delusion, that they should believe a lie: That they all might be damned who believed not the truth, but had pleasure in unrighteousness.” (2nd Thessalonians 2:11-12)
