God has called us to Know him

i believe that God has called us to know him. 

The bible says that some will stand before God on judgement day and say lord i did this, i helped these people i gave to the poor, but God will say i did not know you.

if you just stop to listen to what he is saying "i did not know you" 

my goal is to get as close to God as i can, i want to know him so well, that when he leads i will know his voice and follow.
