50 Now I say this, brethren, that flesh and blood cannot inherit the kingdom of God; nor does the perishable inherit the imperishable. 1 Corinthians 15:50 (NASB)
It is a very dangerous thing to interpret things extra-biblically that occur in our spiritual growth. For instance, in my own walk I was in a very stagnant spiritual state for over a decade from around 1990 until 2004. I had some growth spurts during that time, but they were always followed by years of mediocrity. Then in 2004 God took me through about 8 months of spiritual boot camp. I emerged a changed man. I really thought that I had come across some sort of ‘second blessing’ in which I had entered into a new level of spirituality that was easily accomplished simply following some sort of plan or formula that I could somehow teach to others.
