Though material things play into the meaning of pure from one place, without thought pure becomes a mute point ...
Tit 1:13-16 This witness is true. Wherefore rebuke them sharply, that they may be sound in the faith; Not giving heed to Jewish fables, and commandments of men, that turn from the truth. Unto the pure all things are pure: but unto them that are defiled and unbelieving is nothing pure; but even their mind and conscience is defiled. They profess that they know God; but in works they deny him, being abominable, and disobedient, and unto every good work reprobate.
Would there have been evil without God … would sin have entered into the world without the commandment? is a yes or no question … and irony if your answer is any more than yes or no … it was never about sin, but the process of the soul (Where are you? who told you? Have you eaten?); the tree yields its fruit through obedience … as it does through disobedience … one is full of labor the other, without cost …
"If I had not come and spoken unto them, they had not had sin: but now they have no cloke for their sin."
"And Jesus said, For judgment I am come into this world, that they which see not might see; and that they which see might be made blind. And some of the Pharisees which were with him heard these words, and said unto him, Are we blind also? Jesus said unto them, If ye were blind, ye should have no sin: but now ye say, We see; therefore your sin remaineth."
The Christian and the Atheist fall into the same pit …
Blessed are the pure in heart: for they shall see God. True or false … yay or nay …
To answer your question and keep it as yes and no, would sin have entered the world without God? The answer is yes
Just because there is no commandment does not mean there is no sin. Just because there is no knowledge of God does not mean there is no sin.
We have only to look at the antediluvian society. Each lived as was right in their own eyes, and their imaginations were evil continually. Moses and the Ten Commandments did not come until much later, yet God repented of creating them and they were destroyed by flood.
We are still trying to grasp the impact of that cataclysmic world event. Modern man has decided to deny it, and revert to using their vain imaginations. Neichze said God is dead, and sin grew worse than anything in recorded history.
It is only by the power of Christ and His shed blood that sin is taken away. Though our sins be red as scarlet they will be made as white as snow
Blood of Christ, falling upon the Earth in the agony, save us
Blood of Christ, shed profusely in the scourging, save us
Blood of Christ, flowing forth in the crowning of thorns, save us
Blood of Christ, poured out on the cross, save us
Blood of Christ, price of our salvation, save us
Blood of Christ, without which there is no forgiveness, save us
Blood of Christ, Eucharistic drink and refreshment of souls, save us
Without God, there is only sin and death
With God, there is forgiveness, life and peace
Theme js no process which we could put ourselves through except for faith in the Son of God who loved us and gave Himself for us.
We follow Him not by merely acknowledging His existence, but by obedience, self denial and humility. The process of redemption comes from God, not within us. That process includes forsaking sin and doing good works
