Does God Hear My Prayers When I Am Living in Sin?

How does God's Holy 
Word, the King James 
Bible, answer that 
question?

Psalm 66:18
If I regard iniquity [sin] in 
my heart, the Lord will 
not hear me:

Proverbs 28:9

He that turneth away 
his ear from hearing 
the law [God's Holy 
Word], even his 
prayer shall be 
abomination [what
is hated by God]. 

Isaiah 59:2

But your iniquities [sins] 
have separated between 
you and your God, and 
your sins have hid his 
face from you, that he 
will not hear.

But, here is the 
good news:

1 John 1:9  
If we confess our sins 
[to God in heaven], 
he is faithful and just 
to forgive  us our sins, 
and to cleanse us 
from all 
unrighteousness 
[sin].
