The Holy Spirit is said to reprove from what:
John 16:8: "And when he is come, he will reprove the world of sin, and of righteousness, and of judgment:"
Why be reproved by RIGHTEOUSNESS? BECAUSE MAN'S RIGHTEOUSNESS is DIRTY and DETESTABLE before God.
Isa 64:6,9: "But we are all as an unclean thing, and all our righteousnesses are as filthy rags; and we all do fade as a leaf; and our iniquities, like the wind, have taken us away. … Be not wroth very sore, O LORD, neither remember iniquity for ever: behold, see, we beseech thee, we are all thy people."
Even Men's sacrifices for sin(are only type or symbol of Christ), God take no pleasure. It is only through the ULTIMATE SACRIFICE OF CHRIST THAT SIN BE ATONED AND PAID. CHRIST ALONE CAN SATISFY GOD'S JUSTICE.
Heb 10:6,8,10-12: "IN BURNT OFFERINGS AND SACRIFICES FOR SIN THOU HAST HAD NO PLEASURE. … Above when he said, Sacrifice and offering and burnt offerings and offering for sin thou wouldest not, neither hadst pleasure therein; which are offered by the law; … By the which will we are sanctified through the offering of the body of Jesus Christ once for all. And every priest standeth daily ministering and offering oftentimes the same sacrifices, which can never take away sins: But this man, after he had offered one sacrifice for sins for ever, sat down on the right hand of God;"
Tit 3:5: "Not by works of righteousness which we have done, but according to his mercy he saved us, by the washing of regeneration, and renewing of the Holy Ghost;"
IF MAN WILL NOT ACKNOWLEDGE(REPENT OR CHANGE MIND)ABOUT HIS HELPLESS STATE, SINFULNESS AND DECIDE THAT HE NEED CHRIST to be righteous before God, He can never attain the FAITH TO BE SAVED WHICH IS PURELY TO TRUST IN CHRIST AS HIS PERSONAL SAVIOR.
IF YOU THINK YOUR RIGHTEOUS WORKS CAN SAVE YOU...
THINK 1,000 TIMES & READ BIBLE.
