We only know God in His works, but we are forced by science to admit and to believe with absolute confidence in a Directive Power-in an influence other than physical, or dynamical, or electrical forces.

Do not imagine that mathematics is hard and crabbed, and repulsive to common sense. It is merely the etherealization of common sense.
Interpretation
Mathematics is not as difficult as it seems; it's a refined form of common sense.
In this quote, Lord Kelvin emphasizes that mathematics should not be viewed as an intimidating or difficult discipline. Instead, he argues that it is an abstraction of common sense, implying that mathematical concepts stem from fundamental logical reasoning that is innate to human understanding. By redefining mathematics in this way, he encourages individuals to engage with the subject without fear or prejudice.
In practice
In a classroom setting to encourage students who find math challenging.
We only know God in His works, but we are forced by science to admit and to believe with absolute confidence in a Directive Power-in an influence other than physical, or dynamical, or electrical forces.
In science there is only physics; all the rest is stamp collecting.
There is nothing new to be discovered in physics now. All that remains is more and more precise measurement.
Let nobody be afraid of true freedom of thought. Let us be free in thought and criticism; but, with freedom, we are bound to come to the conclusion that science is not antagonistic to religion, but a help to it.
I need scarcely say that the beginning and maintenance of life on earth is absolutely and infinitely beyond the range of all sound speculation in dynamical science. The only contribution of dynamics to theoretical biology is absolute negation of automatic commencement or automatic maintenance of life.
Science is bound, by the everlasting vow of honour, to face fearlessly every problem which can be fairly presented to it.
Most discoveries even today are a combination of serendipity and of searching.
I have been struck again and again by how important measurement is to improving the human condition.
We do not draw conclusions with our eyes, but with our reasoning powers, and if the whole of the rest of living nature proclaims with one accord from all sides the evolution of the world of organisms, we cannot assume that the process stopped short of Man. But it follows also that the factors which brought about the development of Man from his Simian ancestry must be the same as those which have brought about the whole of evolution.
Science appears to us with a very different aspect after we have found out that it is not in lecture rooms only, and by means of the electric light projected on a screen, that we may witness physical phenomena, but that we may find illustrations of the highest doctrines of science in games and gymnastics, in travelling by land and by water, in storms of the air and of the sea, and wherever there is matter in motion.
Nature - how, we don't know - has technology that works in every living cell and that depends on every atom being precisely in the right spot. Enzymes are precise down to the last atom. They're molecules. You put the last atom in, and it's done. Nature does things with molecular perfection.
All models are wrong, and increasingly you can succeed without them.
