Why do you think sin doesn't exist? We all do things that we shouldn't do.
And God spoke all these words:
“I am the Lord your God, who brought you out of Egypt, out of the land of slavery.
“You shall have no other gods before me. (Exodus 20:1-3).
The first commandment means that God should be the focal point of all of your affections. Your relationship with Him should be the most important part of your life. A perfect example is the rich young ruler Matthew tells us about in the New Testament:
Just then a man came up to Jesus and asked, “Teacher, what good thing must I do to get eternal life?”
“Why do you ask me about what is good?” Jesus replied. “There is only One who is good. If you want to enter life, keep the commandments.”
“Which ones?” he inquired.
Jesus replied, “‘You shall not murder, you shall not commit adultery, you shall not steal, you shall not give false testimony,19 honor your father and mother,’ and ‘love your neighbor as yourself.’”
“All these I have kept,” the young man said. “What do I still lack?”
Jesus answered, “If you want to be perfect, go, sell your possessions and give to the poor, and you will have treasure in heaven. Then come, follow me.”
When the young man heard this, he went away sad, because he had great wealth.
Then Jesus said to his disciples, “Truly I tell you, it is hard for someone who is rich to enter the kingdom of heaven. 24 Again I tell you, it is easier for a camel to go through the eye of a needle than for someone who is rich to enter the kingdom of God.” (Matthew 19:16-24).
It is interesting to see how Jesus talked with the rich young ruler using the Ten Commandments as the starting point in a discussion of "what shall I do to inherit eternal life?" And with those commandments He was able to show the man his self-righteousness. This is an amazing story. The rich young ruler could not even get past the first commandment: He did have another god before the God of the universe, and it was his money. We will all worship something. Whether we are atheists, agnostics, or believers in some religion, we are all worshipers. Where do you turn your mind and heart to gain meaning, fulfillment, control, protection, and significance in your life? What has your affection? What do you meditate upon? When you lay your head on your pillow at night, what do you think about? Who or what is your God? Now ask yourself this question: Have I broken the first of the Ten Commandments?
In Hinduism there is a concept called soul age. Over many many lifetimes, the soul is emanated from God, and slowly returns to God, as molecule of water would evaporate from the ocean, only to be returned to the ocean. When the soul is young, it's also stupid (from anava). Just as children make mistakes because they're young in a particular lifetime, the young soul makes mistakes. Just this morning I witnessed a young soul cursing about his experience of having a store open at 7:02 instead of 7:00. His poor body had an accelerated heart rate. You could say the guy was mad. He was right in the mood to start a confrontation. I was in the exact same situation and I had no anger whatsoever, totally able to accept that situation. So in terms of soul age, one could say I was an older soul, at that moment.
So what you call sin, I call immaturity of the soul. Does the university professor go about yelling and accusing the child in kindergarten of sinning? I think not.
Again, I don't believe in sin, and Christianity is irrelevant to me. Please stop your preaching. You have the right to differ.
