As well, in the Book of Job, chapter 1 and 2: if Satan wanted to find out if Job would indeed curse God to His face (if God would stretch forth His hand against Job), all Satan would have to have done is say the following:
“God, you know everything; We all know this. Please tell me and the rest of all beings in the universe if Job will indeed curse you to your face if you do x, y and z to him.”
Adam and Eve blew it. God knew they would. That’s why He sent His only begotten Son, Jesus. Believe on Him and you will be saved. Plain and simple.
