What does the New Testament say about the heart and coveting?

In the New Testament, both Jesus and Paul stress the significance of the heart in relation to sin and coveting. Jesus, in Matthew 15:18-19, teaches that it is out of the heart that evil thoughts and desires emerge, defiling a person. Likewise, Paul emphasizes in Romans 7:7 that the law reveals the true nature of sin, which includes coveting as a heart issue rather than just an outward action. The transformation that occurs within a believer, highlighted in 2 Corinthians 5:17, shows that those who are in Christ are new creations, where the heart is reformed to desire God’s glory over worldly possessions.
