Success in life is a measure of what you attract to your life by who you become.
It results from the increment of the realities you attract to yourself on the strength of consistent self improvement through knowledge and transformation.
Spiritual growth is engaged, it does not happen by default. The passage of time does not make for growth spiritually.
There is a phenomenon the Bible terms “The Traditions of Men”. This plays a key part in interrupting believers from rising to the pinnacle of their Christian experience. You must steadfastly hold on to your vetted biblical convictions so as not to be swayed.
