God is love

"Is it true that God is love to me as a Christian? And does the love of God mean all that has been said? If so, certain questions arise.
Why do I ever grumble and show discontent and resentment at the circumstances in which God has placed me?
Why am I ever distrustful, fearful, or depressed?
Why do I ever allow myself to grow cool, formal, and halfhearted in the service of the God who loves me so?
Why do I ever allow my loyalties to be divided, so that God has not all my heart?"

That's good stuff from J.I. Packer's book Knowing God, the end of Chapter 12: The Love of God
