"It is not sufficient for any man to run well for a season only. Whatever your attainments may be, and whatever you may have done or suffered in the service of your God, you must forget the things that are behind, till you have actually fulfilled your course and obtained the crown."
Charles Simeon, quoted in Handley C. G. Moule, Charles Simeon, page 166.
Nobody builds equity serving God. It's all of grace. So yesterday doesn't matter any more. Today is a new day to live for Him.
