... there is an intrinsic sense of right or wrong in the human brain...That came from Where?
NIV Romans 2:11-15
11. For God does not show favoritism.
12. All who sin apart from the law will also perish apart from the law, and all who sin under the law will be judged by the law.
13. For it is not those who hear the law who are righteous in God's sight, but it is those who obey the law who will be declared righteous.
14. (Indeed, when Gentiles, who do not have the law, do by nature things required by the law, they are a law for themselves, even though they do not have the law,
15. since they show that the requirements of the law are written on their hearts, their consciences also bearing witness, and their thoughts now accusing, now even defending them.)
NIV 1 Corinthians 4:4
My conscience is clear, but that does not make me innocent. It is the Lord who judges me.
NIV 1 Corinthians 8:6-7
6. yet for us there is but one God, the Father, from whom all things came and for whom we live; and there is but one Lord, Jesus Christ, through whom all things came and through whom we live.
7. But not everyone knows this. Some people are still so accustomed to idols that when they eat such food they think of it as having been sacrificed to an idol, and since their conscience is weak, it is defiled.
NIV Titus 1:15
To the pure, all things are pure, but to those who are corrupted and do not believe, nothing is pure. In fact, both their minds and consciences are corrupted.
NIV Hebrews 9:9
This is an illustration for the present time, indicating that the gifts and sacrifices being offered were not able to clear the conscience of the worshiper.
NIV Hebrews 9:14
How much more, then, will the blood of Christ, who through the eternal Spirit offered himself unblemished to God, cleanse our consciences from acts that lead to death, so that we may serve the living God!
NIV Hebrews 10:22
let us draw near to God with a sincere heart in full assurance of faith, having our hearts sprinkled to cleanse us from a guilty conscience and having our bodies washed with pure water.
NIV Hebrews 13:18
Pray for us. We are sure that we have a clear conscience and desire to live honorably in every way.
