"How great is the love the Father has lavished on us, that we should be called the children of God!" says John, but do we know who our Daddy is? It is easy to acknowledge that we are His children, but we don't always think about WHO it is that is our Father.
Jesus longs for those who will see with their eyes, and hear with their ears. Jesus longs for us to gain insight, an understanding that is almost an "a-ha" realisation in our lives. We can train ourselves to regularly get insight, which will enable us to move into deeper spiritual understanding.
