Just let me finish this...
We've all been there someone (colleague, spouse, child, random stranger) asks us to do something and we say, "just a minute" or "just let me finish this". But it's so easy for that one thing to become another and another and we never do get around to whatever it was.
God won't be kept waiting, however. God will bust in and interrupt our lives in the holiest, most disruptive ways possible.
