Master Hoomer, while there is a lot of validity to your statement, I don't believe it will be of much help to 10 to 12 year olds... which is the point of this forum; to try to get an answer to help JTB (Sonia?)
We are always "with God". We just don't always sense it. It takes dedication, faith, and effort to consciously recognize the divine, but it is possible. As Maize said, the first steps are to open your mind and your heart. You must learn to love everything and everyone, for then you will see that everything around you is divine, and you will begin to sense and connect with God.
