I think we all struggle with grasping the fact that we are made righteous through the finished work of Christ on the cross (2 Corinthians 5:21). Ruth shares the truth of The Gospel with clarity and encourages us to keep our eyes on Jesus. "Perhaps you've tried to outrun lack and limitation with your own resources. Take heart, friend. God desires for you to rediscover, or realize for the first time, that He alone is your sustainer." (Pilgrim, page 150)
"Pilgrim" is a phenomenal book and I hope that you will take the time to read it. It will encourage your heart, challenge your thinking, and nourish your soul.
