free Bibles, but the Gospels only

In the Times Square subway station, I sometimes see people preaching the word of God or at least trying to get people to repent talking about the end of times. These same people hand out lots of reading material including free Bibles. The only problem I see in all this is that these Bibles are only the four Gospels (no Old Testament, no other books from the New Testament).

• This means that we only have the storied of Christ's life, three-year public ministry, crucifixion, death, resurrection and Word (Gospels only).
• Therefore the the prophets, the people of God (Old Testament), the coming of Christ and the letters of the early Church (New Testament) are missing.

Of course, the distribution of at least part of the Good News remains a good idea.
