Really? Can't handle it? Now in a way, there is some theological truth to this statement. Left to myself, with no outside help, I can't choose to put up with a horrific (read minor) annoyance, and am a slave to my tired emotions. But this, of course, is not the case. As a child of God trusting in the finished work of Christ on my behalf (and on behalf of all those He loves) I am not left to myself. I have a power established inside of me that enables me to do that which my sinful nature would never choose to do! Therefore, when I decide to react badly, sinfully to a certain situation, it isn't that I couldn't act in the right way, it's that I wouldn't. I need to do what Paul encourages in Philippians 1:12-14 and to "work out [my] own salvation in fear and trembling, for it is God who works in [us], both to will and to work for His good pleasure."
It's an odd tension, knowing both that God is the One willing us to do good and that it is our responsibility to work, but it is there very clearly in scripture. Maybe it is a little like eating good food. The nutrients strengthen you to do the work, but if you don't actually get up and run you will never accomplish your goal. All analogies break down at a point but you understand my meaning. Pray for the strength to obey, then go an do it whether you understand it or not.
"Oh, the depth of the riches and wisdom and knowledge of God! How unsearchable are His judgements and how inscrutable His ways! 'For who has known the mind of the Lord, or who has been His counselor? Or who has given a gift to Him that He might be repaid?' For from Him and through Him and to Him are all things. To Him be glory forever. Amen." Romans 11:33-36
