There are two ways of reasoning.  The first way is reasoning by direct argument. For example, when the sun rises, you can see the sun and say it has risen. This direct argument is based on observation and experiment. This is direct argument. But there are only one in billion things in this world that can be proven by direct argument. For rest of the things, direct argument is not possible. There we have to use inferential argument.

For example, argument from design shows that design points at the designer. When we study the universe, we find that the world around us has harmony, peace and intelligent design. Everything is so meaningful! Such a meaningful world cannot come into existence without a Creator. The proof is that in the things that humans make, there are defects. When we were sitting in this hall last time, the electricity went out. But the sun never fails to shine. Humans have made a system of electricity, but it often experiences failure.

There are many engineers behind this human system. The other system is that of the sun, which never fails to give sunlight. We cannot explain this without accepting that there is a super engineer behind it all. Only when you accept an engineer can you explain the existence of the powerhouse. The greatest argument for me is: Belief in God is strange or unique. When I look at the trees, sky, sun, moon, I often say: Belief in God is strange or unique but not believing in God is even more strange. I often say these words when I observe at the wonderful world. Belief in God is strange or unique but not believing in God is even more strange. When I believe in God, I choose the less strange option in comparison to the more strange option. Belief in God is strange or unique but not believing in God is even more strange. When I believe in God, I choose the less strange option in comparison to the more strange option. This is a very powerful argument to believe in God. It satisfies me completely.
