The answer isn't really as simple as yes or no.
I have attended Churches where their statement of faith is in keeping with the doctrines of grace. Yet when the pastor teaches on passages that clearly speak on things like election, the pastor can be so vague that even an Arminian can agree. Worship of course is a very important issue and in this day and age it is really hard to find a Church that believes in the RPW and the doctrines of grace; let alone when you throw in another issue such as the roles of men and women in the Church (which by the way is a hit button with me).

So what I am trying to say is, it isn't an easy descision one way or another.
I personally know that when I am not involved in a local body, my spiritual life is hindered. Yet, I also know that how often I have been grieved when what is being preached isn't in keeping with what I believe.
Yet even in those times I have known other believers of like mind in those Churches, where we were able to encourage each other.
I personally am thankful that the Lord brought me to the Church my wife and I presently attend. I certainly don't take it for granted.
