Today's First Reading is taken from 1 Samuel 16. God lets Samuel know that man sees the appearance but he looks into the heart. Time and again, I have assessed a person based upon his appearance and even his speech and I turn out to be wrong. Only God knows what is hidden in the heart. Our hearts are for God alone to see and examine in secret. You could say that to become holy is basically a process of preparing and purifying the heart so that it becomes presentable to the Lord.
