God forbids us to be dissatisfied with what He has given us, and with what He expects of us. He also forbids us to covet that, which does not belong to us according to His will, and which we cannot get without acting against it.
1 Tim. 6:7-9: For we brought nothing into this world, and it is certain we can carry nothing out. And having food and raiment let us be therewith content. But they that will be rich fall into temptation and a snare, and into many foolish and hurtful lusts, which drown men in destruction and perdition.
