Coveting and Idolatry (Ephesians 5:5)

The Apostle Paul gives the warning that if someone covets they are giving into idolatry. If someone gives into idolatry then they do not have the kingdom of God. So, as we all struggle with idolatry does that mean we do not have Christ? If we struggle with coveting does that mean we do not have Christ? How do we proceed to serve the Lord while having this propensity to struggle against his will?
