Can we say confidently that there is no God?
Draw two circles, circle A has knowledge of entire universe, circle B has 10% of our knowledge and 90% of what we dont know. It would be arrogant to say "there is now God" when we stil do not have knowledge about the 90% of universe, the best is "I am not sure if there is a God or not"
Encourage non-believers to find evidence about God
Example; If we look at two statements "there is a cat in this room" and "there is no cat in this room", second statement is much harder to prove. First is we can see, smell, touch, hear the cat in room or look for signs. But the second statement must scrutinize every nook and cranny of room to ensure that there is no cat in the room.
People use wrong measures, criteria that are impossible to fulfill, such as "i will not believe that there is God until i can see him, hear his vioce, or touch him with my hand"
This kind of reasoning is invalid cause makes wrong assumption that can prove Gods existence using five senses, which is logically compared to statements such as "i will not believe that there is a moon until i walk on it" or "i will not believe there are electrons until i see them"; Even though we haven had not chance to walk on moon we can use our eyes, even though we can not see electrons we can see the effects of their existence from the way light bulb gives light. Can not measure something abstract to concrete terms. Even though we cannot prove Gods existence using our five basic senses, the evidence for his existence is very valid. He is spirit John 4:24 and leaves us evidence of his power.
Pantheism is not answer
God of all christian is different from god of those who believe in pantheism (hindu) which unites with the universe which means he is everything and everything in universe is part of god too. It is strange because one part of god can be expect understand everything about god (nature) and whole god or things in nature cannot understand the condition of man. how can material things that do not have personality be part of God the creator who has personality.
First evidence of order in universe (Psalm 8:3-4)
Einstern believed in God the creator while developing the theory of relativity as he saw the law and order of the universe. he knew we did not come about by chance.
e.g ozone layer, our eyes
moral reasons (Rom 2:14-15)
God inscribes what is good and evil in mans heart, hence we have a conscience. The believe of good and evil implies that standard of judement cannot be established by man but by God. For true justive to come about, there must be God, experience in lives of Christians.
