How can I love God more, and show it?

First off, you can purchase a teen study bible and start a one year devotional guide (reading plan) read and memorize scripture it Is your best tool. Do something for someone for free, and when they ask why tell them because Jesus told me too. Trust me it works. Another way is just by loving on people, the bible says to love your friends like yourself and family members. And anytime you can spread his word. P.S. You can read the full bible online for free at Biblegateway.com.
