Building is there. Implies Builder should be there. Creation is there. Creator should be there. I can see the building, which is in front of my eyes, but builder need not stand in front of the building. He will be in his own job. If you want to meet the builder, you should definitely put effort to locate the builder and see him. Likewise Creation is there in front of our eyes. But have we put anytime effort to locate and identify the creator? Instead of that, with least effort we can propagate to others also that God is not there. They are not only blinded, they are making others also blinded. Some people who are theists may become prey for the propagation of this ignorance also unfortunately. The greatest sin on the earth is to be unfaithful.
To identify the builder you should know the identification marks, where he lives, what he does etc.. and we have to enquire if we don't know. This is to say that knowledge is required to identify any person. This knowledge is called divine knowledge if the aim is to identify the Lord, which actually only is to be propagated. Lord created this universe for the enjoyment without any selfish motive and we human beings are enjoying the creation. Like through nice parents, wife, children, beautiful nature consisting of pleasant looking mountains, rivers, sea, nature, changing weather etc.
If we cannot please the Lord, the human life is incomplete. We serve our family members by spending our hard earned money and also physically. Are we not serving family as Servant, and these family members are nearly equal to us. Where as, Lord is omnipotent and requires no help from us, many times satisfied our desires, saved us from mishaps etc. and if we cannot bow our head in front of Him, it is very ridiculous. It is very great honour to serve Him, this is the path followed by His real devotees. These real devotees could overcome ego and always wants to serve Him as servant.
Jesus preached the gospel and His followers participated in His mission as servants for further propagation of divine knowledge. These great devotees never hesitated to serve Lord Jesus and their names have also been known even today.
