Studying the word God isn't something we need to select days, because the word of God is very necessary to our living. Our lives are dependent on the word to survive spiritually, and even physically too. The word is a lamb to our feet and a light to our path. We love the word to study the word consistently.
I keep wondering why people think that they need selected days to study the word. We live in the days were people don't even study the word at all. And I keep wondering why people would stay without studying the word of God. Personally, I study the word everyday and twice at least to grow my spiritual life.
No need to select days to study the word, You need to study the word every time and every day to stay rooted in the spirit helping your spiritual life grow.
