It brought the death blow. This reveals covetousness as the crux of all sin. It is the sin of the heart. There is therefore now no condemnation to those who are in Christ Jesus, who do not walk according to the flesh, but according to the Spirit. The most pervasive of all the commandments.
Covetousness can pop up in any area of life.
Like a great deal of temptation, covetousness slips up on our blind side and attacks us in areas where we least expect. The most revealing of the commandments. It indicates the presence or absence the most basic Christian virtues, faith and love. Covetousness grows out of a basic mistrust of God, especially in his care and provision for us. It therefor robs of one of life's highest blessing, contentment.
