There are many in this world that has faith in God. You know there are few people in this world who ask for to show God to believe. But you know the definition of faith is believing the thing which does not appear now or happening now. Like - When I go and sit in train/bus I have faith that the driver is there (even he may not be in seat when I board) and I also believe that he will take me to my destination. Many believe in a driver but not in God.
Bible says two times in the book called Psalms (in Chapter 14 & Chapter 53, in verse 1) that "The fool hath said in his heart, there is no God." In other we can say that whoever says that there is no God is a fool. Bible gives a correct reply to those who ask us to show God. In the book called Epistle to Romans (in chapter 1, verse 18 onwards) Bible says "For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men ( i.e. who says that there is no God) because that which may be known of God is manifest in them; for God hath shewed it unto them. For the invisible things of him (God) from the creation of the world are clearly seen, being understood by the things that are made, even his 'eternal power' and 'Godhead'; so that they are without excuse". Here Bible says if you 'think' about the created things of this world, you will know and understand the power of God and his Godhead. But the problem with man is he won't apply his god given faculty called 'thinking'. Bible says in the book called Psalms (in Chapter 14 & Chapter 53,in verse 2) that " God looked down from heaven upon the children of men, to see if there were any that did understand, that did seek God". Yea, if man seeks God with understanding he will find God.
For example many of us wear readymade dresses, we wear watches, etc. Most of us have not seen the person who has designed and made our dress or watch. But, we all believe that there is a brain behind them. If anyone says that there is none behind the creation of our dress or watch, we call him insane. Similarly when we look at the creation, the universe, earth, sun, moon, etc., we will understand that there is some brain behind this creation i.e. God. When we further think deeply about this creation, like, how he created and maintaining the universe, we will understand the power of God. In book called Job (chapter 26), Job describes God and says in verse 7 "He stretcheth out the north over the empty place, and hangeth the earth upon nothing. He bindeth up the waters in his thick clouds; and the cloud is not rent under them". In verse 14, he says, "Lo, these are parts of his ways: but how little a portion is heard of him? But the thunder of his power who can understand?" In Psalms 19:1, it is written that "The heavens declare the glory of God; and the firmament sheweth his handywork". So, through creation and by applying our common sense we understand the existence of God.
When we understand this fact, as it is written in Book of Revelation 4:11, we also should worship God along with other worshippers of Lord saying "Thou art worthy, O Lord, to receive glory and honour and power: for thou hast created all things, and for thy pleasure they are and were created".
