God wants our all to grow strong and be in good health. As I read this verse, to my understanding it is giving priority to the requirement of our soul’s health and growth. As our soul prospers, so will our body and life.
The soul is our mind, will, and emotions. The mind here indicates our thought life. The will points to our desires and passions that dictate our choices and decisions. And our emotional health indicates the dictates of our feelings in any given moment.
Our emotions are good and intended to help our lives, but not as the leading role for life. Our emotions can prosper and help us only when they are dictated by right thinking and good choices flowing from the dictates of the Spirit controlling our desires and passions.
The soul is covered in scripture as one part because, to function properly, the three aspects that make our soul must function as one. As Father, Son, and Holy Presence work as one, so must our mind, will, and emotions. When mind, will, or emotion go off in their own direction, separate from the whole, that is when struggle, dysfunction, and instability takes hold of our lives.
Give some focus to soul care today and may your entire being prosper as your soul grows stronger allegiance to God and His ways.
