How Does Reading New Testament Connect With Discipleship?

I cannot envisage discipleship without reading the New Testament. Scripture is written by prayerful people to shape God's people to be disciples of Jesus. There are many passages in the New Testament which tell us to examine ourselves. I would say do both. Read the Bible in huge chunks. Take a day sometime and read a whole book or even two books at once, just craze God and let it wash over you. Or take an hour or two and take one paragraph and drill down into it asking every question you can about every verse you can. And whatever you're doing, whichever of those are somewhere in between, you will find your discipleship is shaped, directed.
