Taking this passage further, there is a process of God creating something in you. Why does God want to create something in you? Because he loves you.
Becoming ‘born of God’ is the start of a process of God doing a good thing in you, not by natural birth, but by spiritual birth.
God’s light can shine on you. With light, we see clearer in the spiritual darkness and the life we have becomes brighter. Then, God can give you a place to grow in. Therefore, you are productive.
Let God do a life enhancing work in your life. It was always God’s intention since creation.
