Pursue Sanctification

I awoke with this scripture reference plastered to my brain~so for serving a purpose that I don't fully grasp I'm sharing it with everyone~Hebrews 12:14 Pursue peace with all men, and the sanctification without which no one will see the Lord. I know most people pursue peace(kind of?), but do we pursue "sanctification"(holiness)? Jesus is our source of sanctification, pursue Him!
