God is perfect and it is illogical to think he can make mistakes. It was Adam and Eve who used their free will to choose wrongly. That wrong choice is the mistake, the evil. It was disobedience and thus sin. Note that we can make a good choice but at the wrong time. A 3 year old child can take a knife to cut an orange and hurt herself. Her intention is good but her timing is wrong. Slight, twisted or untimely views are what Satan uses at times to get us to sin.
They may be proper but inappropriate. He succeeded with Eve and Adam and he succeeds with many of us today. In this book, Can God Make Mistakes? And with Other Answers, the author shows us how to begin to use logic and reason along with the Holy Spirit to recognize these subtleties. To defend our faith and give reasons for what we believe when we have to is our duty. The Bible says, "in your hearts revere Christ as Lord. Always be prepared to give an answer to everyone who asks you to give the reason for the hope that you have. But do this with gentleness and respect," (1 Peter 3:15, NIV).
