In Corinthians Apostle Paul encourages the believers to get off milk and get onto meat, spiritual meat. Studying the word, having quality devotional time, worshipping God etc. takes time. effort and hard work. But in the Christian walk growth this is essential.  If a baby didn’t grow the parents would be very worried, it’s the same with faith. Everyday we need a deeper revelation and understanding about the ways, the will and the word of God.
