Romans 3:22

Romans 3:22 Even the righteousness of God through the faith of Jesus Christ to all those who believe, for there is no distinction;

Genuine believing is to believe in the Lord Jesus by His faith. We believe in Jesus Christ by His faith, for we have no faith of our own. Jesus is the Author and Finisher of our faith. the more we look at oursevels and examine ourselves, the faster our faith disappears.

Faith is an aspect of Christ Himself. In fact, faith is Christ. 

Thus, the phrase "through faith of Jesus Christ" means believing in Jesus Christ by His faith.
