Conclusion
Assuming there’s nothing dramatically wrong with your church life, it should be noted that church membership or attendance is not a random process. A loving God cares for us deeply, and many Christians have personal testimonies about how they ended up in a certain church — and it wasn't necessarily the one they wanted to join!
Sometimes our circumstances can be frustrating where we're planted, and if this lasts long enough it can cause us to seek solace elsewhere, but that doesn't necessarily mean that we should be leaving. In fact, trials and tribulations can often be God's way of helping us to grow — or raising you up to help solve them — and walking away from this can actually be counter-productive.
However, on the flip-side, God does sometimes use adverse situations to wake us up to things, people and places that are no longer meant for us. Perhaps he's calling you to a new church plant, city — or even country? On rare occasions your personal circumstances might be dangerous or even life-threatening; and no one should ever have to face abuse or attacks in the house of God.
In short, this is something that calls for discernment, and it is always worth reflecting prayerfully on why you feel you want to leave your church family. This is where godly counsel is critical. Having a second, third, or even fourth pair of eyes on your situation is highly advisable, and you should pray that God will provide brothers and sisters from within your church or without, who can give you non-partisan, loving and wise advice.
By the same token, do be wary of people whose manner seems more personally motivated and who may be trying to stand in your way. This approach will likely manifest itself in advice which distorts God's word, is overly controlling, coercive or aggressive, or which omits God altogether. Sometimes even our closest friends and family can be the biggest obstacles to God's direction in your life.
Finally, be assured that this article is not written to diminish your deeply-held convictions about leaving; if you're already set on a certain path and you're convinced that God is with you in it, then may God be with you in your faith. However, if you are uncertain in what you're planning, and you haven't yet reached out to fellow Christians who you can trust, please be encouraged to take the time to be reflective and allow God to work through others to help guide you on the path.
Where there is no guidance, a people falls, but in an abundance of counselors there is safety (Proverbs 11:14).
But the wisdom from above is first pure, then peaceable, gentle, open to reason, full of mercy and good fruits, impartial and sincere (James 3:17).
