Agreed.

God made us with free will, because He wanted us to freely want Him, and if we don't want Him, He will not violate that free will. He sees all and knows all, but He wants us to want Him, and to want to share everything with Him.

I'm not sure if it's true that He doesn't need anything... or maybe it's just that He wants us rather than need... he has community within Himself with the Holy Spirit, Jesus, and the Father, yet He wants us.
