Question: The fact that sin has to exist, otherwise no one would worship a god for saving us from it, and also if nothing 
happens unless it is God’s will, then it must have been God’s will for Eve to eat the fruit and introduce sin.
No sin, no need for a savior, no savior, no worshiping a God for saving. Besides, if God made the rule that death was the punishment for sin, then sent himself/his son to be sacrificed so we are saved from that, then why are people worshiping this God? When all it is saving us from is delivering the punishment he intended to all along. It’s like worshiping someone for not beating you up, its like God is cutting you so he can sell you a bandaid and then be praised once your cut has healed isnt it?
It doesn’t make any sense at all.
Answer: You are assuming, first of all, that there is no reason to worship God other than salvation from sin. This is like saying I cannot appreciate Yosemite’s glorious peaks unless I know something of the trash heap. He is eminently worthy of praise because of His greatness. But since He won’t force anyone to worship Him, yet loves us and knows we need to worship Him for our own good, He provides motivation and warning to stay in the right place. Yet when we fail to heed the warning and make the most stupid choice possible anyway, He does not abandon us but provides a way to rescue us that is fair. Your second assumption is that we don’t deserve to be “cut” or experience death for our disobedience. If that wasn’t the fair and necessary consequence for our rebellion against the One who made us, then it was stupid for God to enter our world as one of us and pay that penalty Himself. But if it is the only way to fairly deal with sin then He has done us the most magnificent service anyone could ever do for someone else.
