You will not find a perfect community. They do not exist. Every
church is made up of people in various stages of growth,
including people who have been following Christ for decades and
still get things wrong. That is not a reason to stay away. It
is a reason to go with honest expectations.
Look for a community within a reasonable distance of where you
live. Proximity matters because genuine community requires
regular presence, and regular presence becomes much harder when
it takes significant effort to get there. The best church for
you is not necessarily the most impressive one you could find.
It is one where the Bible is taught faithfully, the gospel is
central, and you can actually be known.
When you find one, commit to it. Not as a consumer who attends
when it is convenient. As a member of a body who shows up
because the body needs you there, and because you need the body.
That kind of commitment, over time, is how the Christian life is
actually lived.
