The Old Testament Prophet Samuel, instructed by the Lord to anoint a king to replace Saul, was impressed by Jesse’s eldest son, Eliab. But the Lord had different plans. As the scripture puts it:
. . . the Lord said unto Samuel, Look not on his countenance, or on the height of his stature; because I have refused him: for the Lord seeth not as man seeth; for man looketh on the outward appearance, but the Lord looketh on the heart.
Applied to each of us individually, The Lord judges us by our thoughts and desires rather than by our outward appearance. How a person may impress us, even if negatively, should not stop us from sharing the gospel with him. As you look at people, look beyond the outward appearance—clothes, beauty, size—and seek to find the good inner qualities
