One true sign that we are growing in spiritually is our knowledge of and respect for the Word of God. NgiWhen we are children in the faith, we have a raw respect for the words of Jesus. The first stage of our growth is to read our bible from time to time. Not much, but a little here and there. We grow even further when we develop a regular discipline of reading, studying and memorizing scripture.
We are really growing when we grow beyond simple bible memorization reading to the point of meditating on scripture and feeding on its truths. We have grown further if we find ourselves developing convictions and attitudes about life based upon what the bible teaches.
We are fully mature when our collective mind and attitudes are controlled by the scriptures.
