"The LORD does not look at the things people look at. People look at the outward appearance, but the LORD looks at the heart." (1 Samuel 16:7)
God sends Samuel to Bethlehem to anoint one of Jesse's sons. Jesse brings his sons before Samuel, beginning with the eldest, Eliab. Samuel looks at him and thinks: surely the LORD's anointed stands here before the LORD. God says: do not consider his appearance or his height, for I have rejected him. The LORD does not look at the things people look at. People look at the outward appearance, but the LORD looks at the heart. Seven sons pass before Samuel and none is chosen. Is that all? Jesse says: there is still the youngest; he is tending the sheep. Samuel insists he be sent for. David arrives, ruddy and handsome with fine eyes. The LORD says: rise and anoint him; this is the one. Samuel anoints him and from that day the Spirit of the LORD comes powerfully on David. The Spirit departs from Saul.
The Catechism identifies the principle of God looking at the heart as the foundation of all Christian moral discernment: the outward act is always evaluated in the light of the interior intention and the state of the heart (CCC 1765). The shepherd boy who should not have been in the line-up is the one the LORD has prepared.
Brothers and sisters, the LORD looks at the heart. This is both comforting and challenging. Comforting: he sees past the appearance that others use to evaluate you. Challenging: the appearance you can manage; the heart is what it is. Ask God to create in you a heart that he looks at and finds good.
Lord God, you look at the heart. Create in us a heart that is worth your looking. Pass over the impressive exteriors and anoint the one you have been preparing in the field. Through Christ our Lord. Amen.
