Adam and Eve made choices before they chose to sin. Saying they did not have a choice before sinning
is simply wrong. If they did not have a choice, you are basically saying God forced them to be disobedient.
He knew they were going to be disobedient and already had a plan in place to deal with that/us.
Here is the mercy of God... there are sooooo many GOOD choices available to us yet, God only placed one evil choice.... and when God put FRUIT on that tree.... it was just testing time...
God wants His children to be wiser than the serpent and harmless as the dove.... choose the good, refuse the evil. Be humble and teachable, and lead by the Holy Spirit... the Spirit of Truth... We are to have NO FEAR of evil, it is just a test.
When we are in an uncomfortable position of choosing between good and evil.... it it just a test. We must learn to choose the good and refuse the evil.
