Many Christians oppose gambling, but in fact the Bible says nothing about the subject.
The Gospels report one unpleasant gambling incident connected with Jesus: “The soldiers, when they had crucified Jesus, took His garments and made four parts, to each soldier a part, and also the tunic.
Now the tunic was without seam, woven from the top in one piece. They said therefore among themselves, ‘Let us not tear it, but cast lots for it, whose it shall be,’ that the Scripture might be fulfilled which says: ‘They divided My garments among them, and for My clothing they cast lost’” (John 19:23–24). This isn’t much to build an antigambling case on.
