“ #1. Spend more time considering evidences of grace in other Christians than you do pondering their sins and weaknesses. You, as a Christian, probably have a much greater ability to see weakness in other believers than to see strength. It is as if you use a magnifying glass when looking for weakness and a telescope when looking for grace.
