1Cor 9:19-23: ‘Become all things to all people’. Gamers are people too. A lot of gamers play games to escape the problems of reality, to feel a sense of achievement and experience something they would not otherwise be able to. They are all in need of the same things as other people but, more so, meaningful relationships and most importantly they need to know Jesus.
Christians are either not representing Jesus in this area or doing a bad job of it. Gamers are deep thinkers and understand the internet fairly well. Christians who seek to witness to the lost in this medium will also need to have a capacity for understanding the ins and outs of the internet.
