What does Christian growth look like?

I will venture to assure you, that though you will possess a more stable peace, in proportion as the Lord enables you to live more simply upon the blood, righteousness, and grace of the Mediator, you will never grow into a better opinion of yourself than you have at present. The nearer you are brought to Him, the quicker sense you will have of your continual need of Him, and thereby your admiration of His power, love, and compassion will increase likewise from year to year. --John Newton
