Do you mean "need," or "use"? God has no need of anything from us; religion is strictly for our benefit. The Scriptures don't endorse your position. Christ said he would found an ekklesia (assembly); Paul said that worship should be conducted in good order. Sounds like religion -- systematic or formalized worship, usually involving a group -- to me.
James had this comment:
Pure and undefiled religion before God and the Father is this: to visit orphans and widows in their trouble, and to keep oneself unspotted from the world. -- James 1:27,NKJV

Thats James opinion.. but he was quite religious.. as most Jews were..
