Do we have a sin nature? Where are the verses? If you ever have the opportunity or maybe the difficult task of having to discuss this with a hardened fellow who denies "Original Sin," I have compiled a few verses here for review. There is a new wing of Fundamentalism that I have never seen before. It seeks to honor Christ and I think it is a backlash to the Antinomianism that is so rampant in our culture. It is a movement that leans heavily on the "will of man" to save. It teaches repentance and faith, but has a heavy emphasis on works. Verses like Matthew 12:50: "For whosoever shall do the will of my Father which is in heaven, the same is my brother, and sister, and mother." and Matthew 7:21: "Not every one that says to me, Lord, Lord, will enter into the kingdom of heaven; but he that does the will of my Father which is in heaven" are employed to defend this perspective. The heavy emphasis on works being necessary for an authentic conversion has mutated into a sheer works-based effort for men to save themselves. It is mainly an effort to remove an excuse for someone. There are those out there who do use "Original Sin" as an excuse not to take their Christianity seriously. These Fundamentalists think that if a man has a "sin-nature," there is no reason that God would be just in condemning him. Therefore, they remove that obstacle so that in their minds at least, God will be just in handing down a fair judgment of an individual. The problem with this idea is that while it may seem logical to the finite mind, it isn't consistent with "all" of Scripture and it also isn't consistent with the verses listed below. Our finite logical ability and our limited state tempts us to "foist" our own ideas of fairness and justice upon the Scriptures. It is part of our sinful nature.
Observation is also a powerful ally. You don't have to teach a child to be selfish, prideful, or even to lie. However, you do have to teach him to be selfless, humble, and truthful. Whether we like it or not, our nature was gnarled by the Fall. We all have a bent toward evil one way or another. I think we are bent toward some sins over others, but it is just "natural" to go our own way. Only by the free-grace of God can anyone see clearly to go His way and find a "supernatural" solution. Matthew 15:19, Jeremiah 17:9, Psalm 51:5, & Ephesians 2:3. I also recommend the following two links to a Biblical study of Original Sin and a proper view of sanctification:
"Then came his disciples, and said to him, do you know that the Pharisees were offended, after they heard this saying? But he answered and said, Every plant, which my heavenly Father has not planted, will be rooted up. Let them alone: they are blind leaders of the blind. And if the blind lead the blind, both will fall into the ditch.Then answered Peter and said to him, Declare to us this parable. And Jesus said, Are you also yet without understanding? Do you not yet understand, that whatsoever enters in at the mouth goes into the belly, and is cast out into the place where the human waste discharges are dumped? But those things which proceed out of the mouth come forth from the heart; and they defile the man. For out of the heart proceed evil thoughts, murders, adulteries, fornications, thefts, false witness, blasphemies: these are the things which defile a man: but to eat with unwashed hands does not defile a man." Matthew 15:12-20
"The heart is deceitful above all things,
and desperately wicked: who can know it?
I the Lord search the heart, I try the reins,
even to give every man according to his ways,
and according to the fruit of his doings." Jeremiah 17:9-10
"Have mercy upon me, O God, according to thy lovingkindness:
according unto the multitude of thy tender mercies blot out my transgressions.
Wash me throughly from mine iniquity,
and cleanse me from my sin.
For I acknowledge my transgressions:
and my sin is ever before me.Against thee, thee only, have I sinned,
and done this evil in thy sight:
that thou mightest be justified when thou speakest,
and be clear when thou judgest.
Behold, I was shapen in iniquity;
and in sin did my mother conceive me.
Behold, thou desirest truth in the inward parts:
and in the hidden part thou shalt make me to know wisdom.Purge me with hyssop, and I shall be clean:
wash me, and I shall be whiter than snow.
Make me to hear joy and gladness;
that the bones which thou hast broken may rejoice.
Hide thy face from my sins,
and blot out all mine iniquities.
Create in me a clean heart, O God;
and renew a right spirit within me.
Cast me not away from thy presence;
and take not thy holy spirit from me.
Restore unto me the joy of thy salvation;
and uphold me with thy free spirit.
Then will I teach transgressors thy ways;
and sinners shall be converted unto thee.Deliver me from bloodguiltiness, O God, thou God of my salvation:
and my tongue shall sing aloud of thy righteousness.
O Lord, open thou my lips;
and my mouth shall shew forth thy praise.
For thou desirest not sacrifice; else would I give it:
thou delightest not in burnt offering.
The sacrifices of God are a broken spirit:
a broken and a contrite heart, O God, thou wilt not despise. Do good in thy good pleasure unto Zion:build thou the walls of Jerusalem. Then shalt thou be pleased with the sacrifices of righteousness, with burnt offering and whole burnt offering: then shall they offer bullocks upon thine altar." Psalm 51 AKJV
"And you has he revived, who were dead in trespasses and sins; wherein in time past you walked according to the course of this world, according to the prince of the power of the air, the spirit that now works in the children of disobedience: among whom also we all had our manner of life in times past in the lusts of our flesh, fulfilling the desires of the flesh and of the mind; and were by nature the children of wrath, even as others. But God, who is rich in mercy, for his great love wherewith he loved us, even when we were dead in sins, has revived us together with Christ, (by grace ye are saved;) and hath raised us up together, and made us sit together in heavenly places in Christ Jesus: that in the ages to come he might show the exceeding riches of his grace in his kindness toward us through Christ Jesus. For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: not of works, so that any man should boast. For we are his workmanship, created in Christ Jesus to good works, which God has before ordained that we should walk in them." Ephesians 2:1-10
