Though Science makes mistakes, it never cheats or fails whilst making them.
This is probably what Max Plank intended when he said that science is always truthful. It does not claim to be error free, but it can claim to be truthfully in search of correct answers whilst getting some wrong. It has a valid claim to being honest, even whilst making mistakes along the way. Each mistake is an advance, as one more mistaken idea is ruled out and the next potential answer is considered, possibly itself to be proven mistaken.
Eventually, science arrives at something that works, which is all that matters to anyone riding in a plane or crossing a bridge. Science may not, just yet, be certain on all truths to be discovered; and it might not even provide ultimate truth, ever, if there is such a thing. It is just truthful whilst it is trying to find the truth, and we can add, also useful.
We cannot love science in the same way we might love the Creator. Just as we cannot have faith in the Creator as we have faith in Science. The Creator will understand this, if he is scientific.
