Book Quote: Finding Filfillment

I haven't read Becoming More Than a Good Bible Study Girl by Lysa TerKeurst, but I love this quote from chapter one:

Fulfillment means to be completely satisfied. How might our lives look if we were so filled with God's truths we could let go of the pain of our past, not get tripped up by the troubles of today, or consumed by worries about tomorrow? Sound impossible? It is impossible when we try to make it happen on our own by doing more good...things. Praying, reading the Bible, doing another Bible study, going to church, and being nice are wonderful and necessary. But just going through the motions of these activities will not in and of themselves fill our souls. They must be done with the great expectation and heart cry for God to lead us into a deeper and more life-changing connection with Him.
