The Netziv, in his commentary on Chumash, explains that the first verse of the priestly blessing "May G-d guard you and protect you" has different connotations for different types of people. For one engaged in business, we ask G-d to bless us with great material success, yevarechecha, and that such success does not destroy our character, veyishmerecha.
G-d's greatest gift to man is that He created us in His image. As heretical as it sounds, man and G-d are, in effect, opposite sides of the same coin. Flowing from this is the notion that all aspects of our relationship to G-d must be reflected in our actions towards man, and our actions towards our fellow man must be reflected in our relationship to G-d. This can best be seen in the aseret hadibrot, which can be read both vertically and horizontally.
Our Sages have long recognized that the desires for money, honour, and sexual gratification are most powerful. Avoiding sin in these areas, something most difficult in practice, makes one worthy of praise—from G-d Himself.
"Rav Yochanan said: Concerning three [people] does G-d proclaim [praise] every day: on a bachelor who lives in a city and does not sin, on a poor person who returns a lost object to its owner, and on the wealthy [person] who tithes his produce in secret" (Pesachim 113a).
