Please explain the concept of being a sinner to me and why we are deemed evil and unworthy and in need of a saviour, I don't understand this concept.
I've skimmed through this thread and thought I might add a few thoughts:
1. It might be better to say, in regard to their moral condition, that Adam and Eve were
innocent rather than perfect. There is only One who is truly perfect, who is God.
2. I have used the following analogy a few times, but it seems it would be pertinent to the line of questioning of the OP:
Imagine a wood carver makes a carving knife. It must be strong and sharp so that it might carve wood well. Such a knife, however, in being able to carve wood also necessarily possesses the potential to cut and pierce human flesh. The intent of the maker of the knife is that it would be used solely to carve wood, but it is impossible to make such a tool without imparting to it the capacity to carve human flesh as well. If someone takes the carver's knife and stabs another person with it, he has exercised the knife's potential for human harm against the intent of the wood carver who made it. Likewise, God has given us the capacity to choose to do what is good and right. But that capacity to choose the good and right also necessarily entails the capacity to do what is evil. Just like the carving knife cannot be made able to carve wood without being able also to carve human flesh, we cannot be made able to choose what is right without being able also to choose what is wrong. And just like the wood carver's intent is that the knife he makes be used to a constructive, creative purpose, God's intent in giving us free will is that we would use it to choose a constructive moral purpose. We may exercise our free will against the intent of our Maker but that no more makes Him guilty of our sin than a person stealing the wood carver's knife to stab someone makes the wood carver guilty of the stabbing.
You are a sinner, not in comparison to the humans around you, but by the assessment of the perfectly holy God who made you. You (and all the rest of us) do not measure up to God's perfect moral standard. As the Bible says, "For all have sinned and fall short of the glory of God." Since God is just, He must judge and punish our sin, and His judgement is dire. God is certainly within His rights to cast every sinner into eternal punishment in hell, but, fortunately, He is also a loving and compassionate God. His love for us compelled Him to make a way for us to escape the eternal damnation our sin is due. That way of escape is the Saviour, Jesus Christ the Righteous. Through his atoning sacrifice on the cross of Calvary, Jesus made a way for you (and all sinners) to escape the eternal penalty of their sin. "For God so loved the world that He gave His only begotten Son, that whosoever believes in him should not perish but have everlasting life."
Selah.
