the preacher said:
ever religion lays claim to the correct god/gods but none explain what they are.
if I were to ask you to find a giraffe, but you'd never seen one, It would be impossible for me to expect you to find one without first providing you with a description of the creature.
if you were to come across an giraffe, you would have no way of knowing if it was the creature you were looking for, without a discription.
So please Define a god.
What are you talking about? Almost every religion describes God in some way if you read the scripture.
For instance, a Hindu Scripture, the Srimad Bhagavatam has an elaborate description of God:
"The Supreme Personality of Godhead has no beginning, no end and no middle. Nor does He belong to a particular person or nation. He has no inside or outside. The dualities found within this material world, such as beginning and end, mine and theirs, are all absent from the personality of the Supreme Lord. The universe, which emanates from Him, is another feature of the Lord. Therefore the Supreme Lord is the ultimate truth, and He is complete in greatness"
"The Supersoul alone is the ultimate controller and creator of this world, and thus He alone is also the created. Similarly, the Soul of all existence Himself both maintains and is maintained, withdraws and is withdrawn. No other entity can be properly ascertained as separate from Him, the Supreme Soul,who nonetheless is distinct from everything and everyone else. The appearance of the threefold material nature, which is perceived within Him, has no actual basis. Rather, you should understand that this material nature, composed of the three modes, is simply the product of His illusory potency"
"Just as the same material elements exist within and outside of all material bodies, similarly, I cannot be covered by anything else. I exist within everything as the Supersoul and outside of everything in My all-pervading feature"
Similarly Jesus describes the kingdom of God:
"Rather, the (Father's) kingdom is within you and it is outside you."
"I am the light that is over all things. I am all: from me all came forth, and to me all attained. Split a piece of wood; I am there. Lift up the stone, and you will find me there"
"It will not come by watching for it. It will not be said, 'Look, here!' or 'Look, there!' Rather, the Father's kingdom is spread out upon the earth, and people don't see it."
