Iron sharpeneth iron;
so a man sharpeneth the countenance of his friend (Proverbs 27:17).
We are all social creatures by God’s design. Surveying His primeval works, the Lord pronounced them all very good (Gen 1:31). However, when He beheld the original, solitary human being, He said, “It is not good that the man should be alone” (Gen 2:18). God considers companionship indispensable. For one thing, our human weakness makes us vulnerable. “Two are better than one; because they have a good reward for their labour. For if they fall, the one will lift up his fellow: but woe to him that is alone when he falleth; for he hath not another to help him up (Eccl 4:9-10). More profoundly, God’s design for the man in His image reflects His own eternal inter-Trinitarian communion, the infinite delight taken in each other by the Father, Son, and Holy Spirit.
