Faith always gets denigrated now a days. Either you hear how it is cr*p, or if not that, you hear it misrepresented and maligned. Sometimes when I hear people speak about it, I get the impression they hate it. Yeah, they hate something Jesus marveled at and commended in people's lives.
1.) In order to believe in something, that something must already have occurred else faith has nothing to cling to.
Have you heard of this reasoning? I hear this all the time. This is a rationalistic view of how faith is depicted in the Bible and it is so erroneous. In the Bible, such as the case of Abraham, people believed in what God says not because God has already brought it about but because of who God is, the only person worthy of our trust. Biblical proof of this in Hebrews 11 where men of faith looked at the promises of God that went beyond their time with respect to fruition.
For example, if I say to you, I shall meet you tomorrow at such a time and place, has that event - that is me, being there, already occurred in order for you to believe or turn up? No. I tell you, the basis of your belief in me is based on what kind of character I am. The basis of you believing my words is backed up by my reputation of being reliable. Now transfer that idea to God.
Abraham, believed God and it was counted to him as righteousness. Abraham believed in many future promises that God gave to him. There is something non-trivial about this phenomenon of believing God, that is why when one does believe, it is always a miracle - a work of God. For faith in God's promises is not something you can easily come by.
2. Another fallacy is - well, do you believe ENOUGH?
This is a red herring. It is like asking your maths teacher to tell you the four sides of a circle. How much faith do I have to believe that Jesus died for me? Can I believe more and enough that Jesus died for my sins? This question which is asked, by surprise, surprise - fellow Christians, denies what Jesus taught about faith as big as the mustard seed. The question only arises if there is a doubt that Jesus did not die for you but the Bible says he did so how much do you have to believe this? This question is not even valid to ask. For the question is not about believing enough, the question is - did he or did he not die for you? The answer has only two possibilities, yes or no.
I am finding it hard to be nice with such people who throw these fallacies around.
Guess who falls for this fallacy? They are people like me who came from Evangelia or Charismania. Having been burnt to dust by the preaching of the Law they throw the baby with the bath water and hang on to the words of Walther and Pieper rather than the words of Scripture and the Confessions. They become another pawn of the cult called repeat-after-me.
