The word translated covet usually refers to selfish desire or lust (e.g., "Lust not after her beauty in thine heart..." Prov. 6:25), and thus speaks directly to the heart's innermost intention, which, even if unacknowledged by ourselves, is always revealed before God: "Your Father who sees in secret" (Matt. 6:6). On the other hand, selfish desire can - if we are willing to be honest with ourselves - reveal to ourselves the condition of our hearts and thus mark our need for deliverance from the power of sin. As Sha'ul (Paul) wrote to the kehillah (congregation) in Rome: "I had not known sin ...except the law had said, 'Thou shalt not covet'" (Rom. 7:7).
Now here is a paradox: How can we refrain from desiring that which we, in fact, do desire? How can we be made free from the endless cycle of desire-sin/desire-sin?
By walking in the power of the Ruach Hakkodesh (Holy Spirit) by the grace of God through Yeshua the Messiah: "Walk in the Spirit, and ye shall not fulfill the lust of the flesh" (Gal. 5:24, KJV).
May God help you walk in His Ruach always....
