“I will ask the Father, and He will give you another Helper, that He may be with you forever; that is THE SPIRIT OF TRUTH, whom the world cannot receive, because it does not see Him or know Him, but you know Him because He abides with you and will be in you. …” John 14:16-17, 16:8-11
As a Christian who believes Jesus is the way, the truth, and the life, I don’t believe I’ve seen anything that makes me sadder than this ideology pictured below that says there is no such thing as sin.

It is true that, apart from God, our conscience does not recognize sin. Our conscience is dead to God, separated from Him, unable to know His righteousness so we can see sin’s contrast and the judgment of God against it. For that, we must have the work of the Spirit of God, drawing us to God and empowering our realization of how our lives fall short of God’s glory, “for all have sinned and fall short of the glory of God.” (Romans 3:23)
To believe that sin does not separate us from God is to believe the lie of Satan, “…You surely will not die! For God knows that in the day you eat from it your eyes will be opened, and YOU WILL BE LIKE GOD, knowing good and evil.” (Genesis 3:1-5)
You see, they were already like God – we were created in His image, purely good, with no evil in them. Their conscience was pure, having no thought of sin, for they were like God in all His goodness, following Him in trusting purity. Then the devil led them to doubt the goodness of God and sin entered the heart of humankind, separating them from God and deadening the purity of our conscience.
Now, apart from the help of the Spirit of God, we cannot discern our sin or understand sin’s nature, because we cannot know God. The Devil will deceive us into thinking we know God, leading us to a type of god, a false god, if it will keep us from understanding our sin nature and our need of a Savior. Without God working to draw us to truth and His Spirit opening the eyes of our heart to discern sin in us, separating us from God, we cannot acknowledge need of the Savior when we refuse to believe sin exists and our conscience is deceived. We are lost forever, separated from God and doomed to an eternity without Him, never to know intimacy with the One True God.
“And He, when He comes, will convict the world concerning sin and righteousness and judgment; concerning sin, because they do not believe in Me; and concerning righteousness, because I go to the Father and you no longer see Me; and concerning judgment, because the ruler of this world has been judged.” John 16:8-11
“Let us draw near with a sincere heart in full assurance of faith, having our hearts sprinkled clean from an evil conscience and our bodies washed with pure water.” Hebrews 10:22
