Don't refuse to do what God tells you to do. Honestly, I used to get mad and stay mad and I knew that is not what God wanted. I needed to stop fighting what God needed me to do. However long I was stubborn that was how long I was miserable. The longer you put off what he wants you to do, the unhappy you are going to be. He eases and refreshes your soul, your soul is the hidden person of the heart. "I am gentle, meek, humble" and you will find relief, ease, an internal vacation. Even if you laying down and resting your body, but your mind is worried, then you aren't resting, if your resisting God's will in something then you are not resting.
Serious minded Christians eventually learn what it is to have peace, I am addicted to peace, I don't even want to be a little bit upset. God never gives us more than what we can handle, he provides the way out, there is no point in saying 'I can't do this' if it was given to you then you can do it. He never allows more to come on us then what we can bear, with every temptation he also provides the way out.
"It's our attitude, as long as I kept trying to change my husband, there was no peace in my soul because I always had thoughts about everything he did" - Joyce
Some of you may be in situations that you never should of gotten in to, but God does put us together with who and what we need, normally they are very different from us but we should see that as a benefit because that person has what you don't have. They then become a power unit together.
