In Leviticus 5:17-19 (ESV) & Leviticus 6:2 (ESV), we see that God is ever present (i.e., omnipresent) in our lives. This includes, according to these two passages, when one fails to fulfill one’s obligations to others. This includes when one “finds” things that were “lost”.
When one’s obligations to others are not fulfilled, according to these two passages, one’s obligations (or relationship) to God is also unfulfilled. I’ve heard people say that as long as they keep their promises to God (really easy if none are made), everyone else does not matter. These two passages from Leviticus make the point that everyone else does matter. It is not just a one way relationship between the individual and God, but between the individual and other individuals. Deuteronomy 6:5, Mark 12:30 & Luke 10:27, emphasize this in another way.
Just as God is present when the obligations between individuals are broken, God is present when love is spread between individuals:
35For I was hungry and you gave me food, I was thirsty and you gave me drink, I was a stranger and you welcomed me, 36I was naked and you clothed me, I was sick and you visited me, I was in prison and you came to me.’ 37Then the righteous will answer him, saying, ‘Lord, when did we see you hungry and feed you, or thirsty and give you drink? 38And when did we see you a stranger and welcome you, or naked and clothe you? 39And when did we see you sick or in prison and visit you?’ 40And the King will answer them, ‘Truly, I say to you, as you did it to one of the least of these my brothers, you did it to me.’
While love is displayed here in a certain way (and, I believe, taken out of the context of scripture by too many advocates of social justice), and doesn’t cover the entire scope of the “social contract” (including discipline), it shows that God is present between the interaction of all of His people. Thad does not mean that all are saved, or that all are doing the will of God, but that God is present no matter what.
