Why can't it be just about experiencing the love of God? Why not just about knowing the Holy Spirit, living by the wisdom in the Bible?
Instead, new believers have to feel guilty about their Sin. Let's be honest, most people are not sinners but losers. They struggle in their jobs, their finances, their health etc.
They struggle to pay the bills, to find someone who actually cares about them.
They feel normal human emotions like anger, frustrations, hate, even lust.
Why is that evil?
Now such a person would love to experience the love of Jesus & the guidance of the Holy Spirit.
But to reach there, they first have to confess their sins, feel bad about themselves.
It is almost as if sin is the key concept in the Bible.
My parents know me with all my shortcomings. They still love me, and never ask me to confess my so called "sins" everyday for them to love me. Why is it different with God the Father then?
If Christianity was more about spreading the love and forgiveness of Jesus, and less about the condemnation of Sin - we would have lot more believers. Who doesn't want God as a personal friend?
And just for the sake of argument, here is what other religions say on the topic of sin:
Hinduism: The concept of Sin doesn't even exists. They have more of a guidelines about living an ethical life.
Islam: The concept of Sin exists, and good deeds must be performed regularly to outweight the quota of sin in a person's life.
Buddhism: The concept of Sin doesn't exists. "Paapa" or "Punya" are towards another person, whereas Biblical Sin is against God.
