Scripture says that when we give our allegiance to Jesus, his Spirit makes its home in the core of our inner being. Since, all of life proceeds out of this core, the Spirit begins to give input into a person’s core, and it flows out into his life.
(Many people use the word “heart” to designate this core. It feeds into the person’s thoughts, words, and actions. And, therefore, it affects their life. I tend to see “heart” as a figure of the entire inner man. So, when god speaks to my heart, he speaks to the whole package.)
As the spirit gives input at this most fundamental level of our lives, we experience transformation starting at this most fundamental level. It then flows out to the outer places of life. Some people view this as a change in spiritual DNA.
So, as the Spirit splices new “DNA” into our hearts, we begin to live as the spirit lives, as Jesus lives. And Scripture says there are certain results that occur in our lives as this transformation process continues, and should occur in increasing measure.
The first in importance is love. The longer a person walks with Jesus, the more that love should be apparent in their lives. With joy, peace, patience, kindness, goodness, faithfulness and discipline appearing and growing.
