New birth changes things and people. This is ultra-important for those connected to kingdom work. We will be changed to keep changing. God calls it growing toward maturity. Change matures. To fight it is to remain as a child; childish.
Jesus responded to Nicodemus that one born again is like the wind; going one direction and then another. This is the epitome of one concept; change.
When this trait is prominently rebuked a couple of things happen. The status quo becomes the norm from which future truth is assumed. Plus, God's interaction becomes withered. I believe the Word calls it grieving the Spirit.
What this move of birth does for us is it thrusts us into actual faith. We are immediately dependent upon Something larger than our understanding. Our diagnostic skill fades as God has such superlative style which makes our status quo look so.....status quoish.
Regardless of age, we are to live brand new. We are born again to live from an entirely new scheme of things. We are not to take our old ways and make them nicer. We are to be pushed from the womb of the kingdom with a totally new experience....an Abundant Life experience.
The major factor in the new birth truth is change is coming and nothing will change that.
