For everyone who has been born of God overcomes the world. And this is the victory that has overcome the world—our faith.
1 John 5:4 (ESV)
For this reason I remind you to fan into flame the gift of God, which is in you through the laying on of my hands. For the Spirit God gave us does not make us timid, but gives us power, love and self-discipline.
2 Timothy 1:6-7 (NIV)
