The greatest need you and I have-the greatest need of collective humanity-is renovation of our heart. That spiritual place with in us from which outlook, choices, and actions come has been formed by a world away from God. Now it must be transformed. Indeed, the only hope of humanity lies in the fact that, as our spiritual dimension has been formed, so it also can be transformed.
Dallas Willard warns us too of the "cost of non-discipleship." We may be able to live with some pain, but when our whole self becomes more and more rotten, the cost is far greater than dealing with the problem as soon as possible. This is why I think following Jesus, though challenging, is much easier than following anything else. The world has nothing better to offer me. Jesus has come to right my wrongs and to make me refreshingly new.
There is absolutely nothing in what Jesus himself or his early followers taught that suggests you can decide just to enjoy forgiveness at Jesus' expense and have nothing more to do with him.
We should, to begin with, think that God leads a very interesting life, and that he is full of joy. Undoubtedly he is the most joyous being in the universe. The abundance of his love and generosity is inseparable from his infinite joy. All of the good and beautiful things from which we occasionally drink tiny droplets of soul-exhilarating joy, God continuously experiences in all their breadth and depth and richness.
