To “contine in God’s kindness” (Romans 11:22) does not call me to prove my devotion to serve God; God calls me to rest in his devotion to save me. The focus is not on my doing to please him, but on his doing to pardon me. It is not on my commitment to stand for him, but his commitment to die for me. My relationship to God is not based on the progress of my kindness and goodness, but on the perfection of his kindness and goodness expressed in the cross.
When those truths begin to sink into my heart… I begin to change… big time. My devotion to Jesus grows and my doing has a vastly different motive.
