Genesis 3:9-10

(9) But the LORD God called to the man, "Where are you?" (10) He answered, "I heard you in the garden, and I was afraid because I was naked; so I hid." 

So many people doubt GOD exists because they have occassionally prayed for something and didn't get it. Seeking GOD is not an easy task because it is we who have actually hid ourselves from HIM through our sin.

The fact is, GOD is actually seeking us and is providing every means possible to facilitate our reconciliation with HIM. Before we can allow HIM to find us, we must first accept Jesus Christ as our savior and truly believe that He is GOD's Son. After this, we have to do our best to repent and to avoid sinning as much as possible. GOD knows we aren't perfect and that we will once in a while but if we diligently do our best, HE will eventually find us.
