Parents are like God because you wanna know they're out there, and you want them to think well of you, but you really only call when you need something.

This quote is suggesting that parents are similar to God in that we want to know that they are always ‘out there’ for us, like we hope God is. We want our parents to think highly of us, just like we want to please God. But the difference is that we usually only ask for help from our parents when we are in need, while we hope that God is always with us regardless.
