Having studied the scriptures from a new, more authentic ("Jewish", if you like) perspective, then you will not help but be challenged in how we, as Believers, put that into practice in our lifestyle.
Church traditions must fall by the wayside in deference to the authority and teaching of G-d Himself in scripture.
This will often mean being more "Jewish" in lifestyle and appearance, but it is essential to say that what is truly important is to live as the Bible states, with the sayings of Christian teachers and Jewish Rabbis coming in second place to the Word of God itself.
For those having limited experience with Jewish beliefs, Robin Sampson's book is a wonderful way to really get started. It's all been researched and easily laid out so there is limited prep time and you can move on through the holidays quickly, and it's fun.
We love being able to tie our family's beliefs back to where they began and teaching our children that our belief began with God's chosen people and is as real and meaningful today. If you want to bring the origin of Christianity into your home to study and practice, this is the book.
