Should Followers of Yahuah, The God of Abraham, Isaac, and Jacob, participate in “holi-days”?

Yahuah changes not. How has He always felt and what do we see about His character regarding His people participating in pagan practices? We will go thru some Scriptures (always read the whole chapter of the verses I quote) and a little history. Yah must have the final say about how we live our lives because if we do, we are god and there is no room for Him. Shalomie Homie
