Christians, why do you insist your beliefs are based on blind faith?

..when God offers ample evidence for his existence, and nowhere command us to believe in spite of the evidence to the contrary?

A blind faith will surely lead to instability. I have questioned my faith since day one, and have searched and found answers. But you don't even need the Bible to know God exists, otherwise the Bible itself would not say:

Rom 1:20 For since the creation of the world His invisible attributes are clearly seen, being understood by the things that are made, even His eternal power and Godhead, so that they are without excuse,

Rom 1:21 because, although they knew God, they did not glorify Him as God, nor were thankful, but became futile in their thoughts, and their foolish hearts were darkened.

We know from personal experience that intelligible results do not just happen from explosions. We have caused explosions (note that these explosions have an intelligent cause, US, while big bang cosmology offers an explosion without a cause), and we have also designed and created things. Observation leads us to the conclusion that design and creation produces order and that explosions produce chaos, unless directed by intelligence.

We see God's triune nature in all of creation through Atoms being comprised of protons, neutrons, and electrons; and the universe consisting of space, time and matter. Objects all have length, width and depth. Three dimensions, three persons of the Godhead.

We can see the veracity of God's word in that it exists intact after centuries, where other literary works have not been able to, prior to the printing press.

We have so much evidence that we should be presenting it, not hiding from it. It is not "science versus religion", it is "religion versus religion" because natural cosmology and evolution are PRESUMPTIONS made from the evidence, not direct observation of the evidence, and creationism brings presumptions and interprets the evidence adequately in a different way.

Our "trump card" should be logic itself, not pitting logic against faith! Faith IS LOGICAL! A universe governed by randomness (lack of any intelligent origin) and lawlessness is totally illogical in the face of the intelligibility of the universe!
