Satan comes to rob kill and destroy.
And that's why we have to pray to God and ask for His help.
A great childrens song about this is:


O be careful little eyes what you see
O be careful little eyes what you see
There's a Father up above
And He's looking down in love
So, be careful little eyes what you see


O be careful little ears what you hear
O be careful little ears what you hear
There's a Father up above
And He's looking down in love
So, be careful little ears what you hear


O be careful little hands what you do
O be careful little hands what you do
There's a Father up above
And He's looking down in love
So, be careful little hands what you do


O be careful little feet where you go
O be careful little feet where you go
There's a Father up above
And He's looking down in love
So, be careful little feet where you go


O be careful little mouth what you say
O be careful little mouth what you say
There's a Father up above
And He's looking down in love
So, be careful little mouth what you say
