How does the Lord Jesus work? He works by His truth. He works by his love. He works by His Holy Spirit. Now, how can a truth operate within an individual if the truth is not believed? Unbelief blocks the advance of the power of God in a person. The same is true of His love. How can His love bless and cherish if it’s not trusted? You may have someone who loves you profoundly and who does everything for you. But if you look with suspicion at every act he does, that love can never really become operative for you. Suspicion of love is the end of loves working.
