Jude 1:20-21

But you, beloved, build yourselves up on (the foundation of) your most holy faith (continually progress, rise like an edifice higher and higher), pray in the Holy Spirit, and keep yourselves in the love of God, waiting anxiously and looking forward to the mercy of our Lord Jesus Christ to eternal life. 

We should consider our faith a never-ending building project. Each level is a different phase requiring different levels of expertise. Our knowledge of God and our depth of faith continue to increase with each new level of experience we gain from life. The Bible is the plan or blueprint we constantly refer to and keeps us on track.
