In developing spirituality, our relationship with God is enhanced but without mental development, our relationship and sustained impact on our material world will be limited.
Jesus did not only wax strong in the spirit but was also filled with wisdom. Luke 2:40.
Mental development will limit platform for expressing (communicating) spiritual virtues.
Mental capacity is as important as spiritual virtue.
Low or lack of mental prowess will tamper with the coordination of spiritual virtues.
Spiritual strength and mental prowess go together like hand in glove.
As you grow in spirit, keep developing your mental prowess. Luke 2:40-49.
