Is it possible to believe in God and not go to church? Isn't that too rude?
It's possible and many think that it's okay to do that. But increasing your faith is another thing and attending church is gonna play a role for it.
The point is that there is less strength of faith without the connection that the churches bring.

And this is true, the strength comes with gathering and praising in the church together.
As what Hebrews 10:25 says:
not forsaking the assembling of ourselves together, as is the manner of some, but exhorting one another, and so much the more as you see the Day approaching.
