[2 Peter 1:5-8] is a good place to start. (I like the NIV version) Also, you might want to look at [Ephesians 4:17-32] where Paul talks about "putting off" the old man and "putting on" the new man. And in [Ephesians 6:10-20] Paul talks about putting on the whole armor of God and praying for boldness. [Romans 5:3-8], [James 1],[Philippians 2:5-16], [Philippians 3:8-16], and[Philippians 4:4-8] are good too. Also, if you're up for a good study, "Experiencing God" by Henry Blackaby is an excellent one about building a relationship with God.
