The Bible is quite clear – man has the God-given power to choose to do good or evil, to obey God or not to obey Him.
When I read scripture, that's not what it says. First of all it clearly says the knowledge of good and evil was forbidden by God not given by God. But the serpent through subtlety persuaded the woman, and she in turn persuaded the man to disobey God. Moreover, we know men cannot simply choose to obey God since men thinking they had chosen to serve God killed Christ and those men of God who preached the Gospel.
Did you personally choose for yourself to serve God or were you forced/coerced to serve Him?
It has always been in me to desire to serve God as far as I can remember. I don't ever remember choosing this.
"choose for yourselves this day whom you will serve" (Josh. 24:15)
In this the love of God was manifested toward us, that God has sent His only begotten Son into the world, that we might live through Him. In this is love, not that we loved God, but that He loved us and sent His Son to be the propitiation for our sins. 1 John 4:9–10 (NKJV)
But we know the people before Joshua chose that day to serve God, but in the end they didn't. That prompts me to wonder why? Freewill teachers would simply say because they chose not to afterward even though before they had chosen to. Well I know that, but that does not suffice in answering the question. The best clue is Joshua saying this: Joshua 24:19
19 Joshua said to the people, “You are not able to serve the LORD. He is a holy God; he is a jealous God. He will not forgive your rebellion and your sins.
So why do men rebel and sin? I say it is because we have a false image of god that is vanity.
To that end, the scripture you provide, 1John 4: 9-10 is quite telling, for God is revealed through His Love toward us in that He gives His own son for our sins. How can such a God be untrustworthy? Moreover, what manner of darkness dwells between man and God, that God would have to gve up His own son so as to destroy it?
