God demonstrated this ability to transform with how he changed the physical form of the serpent when judged. That way God could keep men from regathering into one herd again, and keep them located where they were best equipped to live in. Not all answers in the Bible are directly stated as some wish they were.
And this is my prayer: that your love may abound more and more
in knowledge and depth of insight." Philipns 1:9
Its not all going to be spelled out for us in black and white as some stubbornly demand it to be. Insight requires gaining an abundance of Scriptural knowledge. Gaining more and more, as the Holy Spirit in us will also be causing our love to abound more and more as we gain more and more sound doctrine.
As a rule, such quality teaching is not to be found in the halls of conventional, conformist, mainstream denominational churches. This life demands intelligent autonomous pastor teachers whom the Holy Spirit has a dedicated life for study and teaching.
James 3:1 tells us that if God had His way only a few should be teaching. Yet, we find many teaching where there should not be. Satan is out to confuse and obfuscate. That's the fight for faith! It will require personal suffering for a season as like when in battle. Its war. War for our minds.
Yet, the battle is the Lord's. Many wish to prove to God that they can do it when God wants us to become grace oriented knowing that we can not do it in ourselves. That He must do it through us. That's when many distort the Word and then get caught up in another spirit. A different Jesus.... and think its the same. By grace we are saved. Not of ourselves. The proud never get it right.
