Repentance is a change of thinking that leads to a change in actions. It is not a one-time event, but a lifestyle.

Henri J. M. Nouwen
Gratitude… goes beyond the “mine” and “thine” and claims the truth that all of life is a pure gift. In the past, I always thought of gratitude as a spontaneous response to the awareness of gifts received, but now I realize that gratitude can also be lived as a discipline. The discipline of gratitude is the explicit effort to acknowledge that all I am and have is given to me as a gift of love, a gift to be celebrated with joy.
Charles Haddon Spurgeon
You say that you are a Christian; do you live like a Christian?
