Atheism is basically lack of belief that God really exists. Where do you think nature originated from and who controls it? There must be someone behind all these and I know that it is God. What He has done for me and I have seen Him do to others will never allow atheism accumulate in my Christian life. Those who write challenging believers as to why they think God exists, are only inflicting wickedness to the world and I pray that one day they get out of that timidity and come to light.
