Sons and Daughters of God: We Shall Not Be Covetous, February 28

 Promises to All Who Keep God's Law of Love

Thou shalt not covet thy neighbour's house, thou shalt not covet thy neighbour's wife, nor his manservant, nor his maidservant, nor his ox, nor his ass, nor any thing that is thy neighbour's. Exodus 20:17. 

The last commandment condemns covetousness. Every selfish desire, every degree of discontent, every act of overreaching, every selfish gratification works to the strengthening and developing of a character which will destroy the Christlikeness of the human agent, and close the gates of the city of God against him. Letter 15, 1895. 

When ... angels come to minister to those who shall be heirs of salvation, and witness the exhibition of selfishness, of covetousness, of overreaching, and benefiting self at others’ disadvantage, they turn away in grief.... In no way could the Lord be better glorified and the truth more highly honored, than for unbelievers to see that the truth has wrought a great and good work upon the lives of naturally covetous and penurious men. If it could be seen that the faith of such had an influence to mold their characters, to change them from close, selfish, overreaching, money-loving men, to men who love to do good, who seek opportunities to use their means to bless those who need to be blessed, who visit the widow and fatherless in their affliction, and who keep themselves unspotted from the world, it would be an evidence that their religion was genuine.... Those who profess to be waiting and watching for the appearing of their Lord should not disgrace their profession by bantering in deal and standing for the last penny. Such fruit does not grow upon the Christian tree. Testimonies For The Church 2:238, 239. 

The tenth commandment strikes at the very root of all sins, prohibiting the selfish desire, from which springs the sinful act. He who in obedience to God's law refrains from indulging even a sinful desire for that which belongs to another, will not be guilty of an act of wrong toward his fellow-creatures. Patriarchs and Prophets, 309.
