In this verse, the Apostle Paul highlights the grace of God and the overwhelming nature of His forgiveness. He emphasizes that where sin abounded, grace abounded much more. Despite the multitude of our transgressions, the love of God is greater still. This truth is a source of comfort and hope for all who trust in Christ.
Without the Law, Paul would not have been aware that covetousness was a sin. The Law serves as a standard given by God that allows us to measure ourselves against His perfect standard of holiness. Through the Law, we are able to identify our faults and failings, which in turn helps us recognize that we are sinners in need of a Savior. The Law's primary purpose is to lead us to Christ for Salvation, as we acknowledge that He paid the price for our sins through His death.
As we come to recognize the depth of our sin, the grace of God and the forgiveness we receive by faith become more precious. The more we see our faults, the more God's unmerited favor is revealed to us. Let us give thanks and praise His holy name for His abundant grace and mercy.

Dear Heavenly Father,  I thank You for Your incredible grace that abounds towards me, even in my weaknesses and failures. Help me to understand that the more sin is exposed in my life, the more precious Your grace and forgiveness become. Thank You for sending Your Son to die for my sins and for declaring me righteous before You. May Your grace continue to be poured out upon me, and may I always praise Your holy name. Strengthen my faith in You, and help me to walk in the light of Your grace every day. 
In Jesus's name I pray. Amen.
