from Preaching Christ Crucified

“But unto them that are contentious, and do not obey the truth, but obey unrighteousness, indignation and wrath, tribulation and anguish, upon every soul of man that doeth evil, of the Jew first, and also of the Gentile” (Romans 2:8-9). The judgment of those who are not in Christ, who have not been redeemed by His atoning Sacrifice, who have not been forgiven by the shedding of His precious blood, who have not been declared righteous by the imputation of His perfect life, will be condemned for every idle word, every idolatrous thought, every impure motive, every insidious action.

“For there is no respect of persons with God” (Romans 2:11). God will judge all: the righteous in Christ and the wicked in sin, without partiality and in absolute perfection because He is unchangeable in His being, wisdom, power, holiness, justice, goodness, and truth.
