Many people do not want to hear the word sin because we are in the new covenant. Yes we are in the new covenant, but that alone will not save anybody except for those who have accepted Jesus Christ as their personal Savior. The bible makes it very clear that everyone who believe in Him will have eternal live (John 3:15).
The only reason why God sent Jesus Christ His only begotten Son to come on earth was to have man’s sin debt paid once and for all through His death on the cross of Calvary.
The beauty of the cross is that we have all been given a new identity as redeemed, children of the most high God, and joint heirs with Jesus Christ.
It is what Jesus Christ accomplished on the Cross that allows us to confess with our mouth the Lord Jesus that God has raised Him from the dead “For with the heart man believes into righteousness and with the mouth, confession is made into salvation (Romans 10:9-10).
If our God knew from the beginning that we will struggle with sin and made sure that there is a solution to the sin problem, it is futile to deny it or pretend it does not exist.
A good example of denying the reality of sin in our lives is King David who in the process of trying to cover or pretend that he did not commit any sin ended up committing more sins (Samuel 11:6-13). This is typical of what happens in real life while trying to make sure that sin is not exposed which results in executing more evil plans to keep sin hidden.
Our first parents Adam and Eve did not just eat the fruit but added more sin by trying to hide from God as they had now realized that they were naked which they never knew before eating the forbidden fruit.
It is sad to live outside of the things of God because sin is preventing us from having full communion with our Heavenly father yet we keep on denying that sin doesn’t exist. This is not a place to be as it can drain us of our resources as we are not able to do certain things because of fear of being exposed. “Be glad in the Lord, and rejoice in His righteousness and shout for joy, all you who are upright in heart (Psalms 32:11).
