I do not know about you, but like so many Americans, I am overweight. If I had to put a number on it, I would say 60 to 80 lbs overweight.
In the past losing weight was pretty easy. I just eat less carbs and dairy and the weight would almost fall off. However, being in my 50s, the weight does not come off as easy.
Back in my 20s, 30, and even 40s, it was not really hard to decide to lose the weight. I just did it. However, these days it seems really difficult. It is almost as though I have no will power to resist those foods.
I have made a pact with myself that I would not eat carbs such as anything with flour or sugar after 1PM. For the most part I have done well, but it takes a lot of effort. If I can slowly get the carbs/sugars out of my life, then I feel like I could start to lose the weight once again.
I mention all of this because of will power. In all honesty, there is not much we can do on our own. We need God to help us, but so many and myself is included in this, try to do everything by ourselves. If I try not to sin, it feels like I sin even more.
Romans 7:15-20 New International Version (NIV)
15 I do not understand what I do. For what I want to do I do not do, but what I hate I do. 16 And if I do what I do not want to do, I agree that the law is good. 17 As it is, it is no longer I myself who do it, but it is sin living in me. 18 For I know that good itself does not dwell in me, that is, in my sinful nature. For I have the desire to do what is good, but I cannot carry it out. 19 For I do not do the good I want to do, but the evil I do not want to do—this I keep on doing. 20 Now if I do what I do not want to do, it is no longer I who do it, but it is sin living in me that does it.
In short Paul was saying he does not have the will power to resist doing what he does not want to do nor can he do what he knows needs to be done. Why?
If we could accomplish everything on our own, there would be no need for Go, but that is not how God wants us to be. He wants us to need Him, to have a relationship with Him, and to trust Him.
Of course like all things in life God has given you the choice. Go and attempt to do what you know should be done and resist what you know should not be done on your own or ask God for help. My advice is go to God. Do what you can do and then leave the rest to God. I pray that you choose wisely.
