What is faith? part 4
Another scripture sometimes used to support the notion of "belief without evidence" is John 20:29 which says, "Because you have seen me, you have believed; blessed are those who have not seen and yet have believed." Again, it is wrongly assumed that "not seeing" equates with "not having reasons to believe," which is clearly false, and the context bares this out. In the context John writes, "But these are written that you may believe that Jesus is the Christ, the Son of God, and that by believing you may have life in his name" (John 20:31). The entire gospel of John, then, is an apologetic. John was giving reasons to believe in Jesus. He would've been in a hopeless contradiction if, on the one hand, he gave reasons to believe, and then on the other hand told us "blessed are those who believe without reasons." Thomas had prior reason to believe in Jesus even before he saw him. He had the testimony of his companions that they had seen Jesus alive. So the lesson being given in the story of doubting Thomas isn't that we should believe without reasons, but that we are blessed to have a basis for belief in Jesus without having to see him with our own eyes.
One other passage used to support blind faith is 2 Corinthians 5:7, which says, "We live by faith, not by sight." Again, lack of sight is wrongly taken to mean lack of reason. If we keep in mind Hebrews 11:1, we can see that the contrast between living by faith and living by sight is not a contrast between living without reasons and living WITH reasons, but rather, it's a contrast between living with hope and living with the realization of our hope. We live by faith in the sense that we hope for what we don't yet have rather than by having the thing we are waiting for, namely the resurrection. Check out the context, and you'll see how well this understanding fits. Paul is talking here about our desire to be with Jesus, so he's clearly talking about hope for something in the future. He's not talking about believing something we have no reason to believe.
