Do you get the sense that this life can’t be all there is? Somehow, you know deep down, there has to be more to life than this? And we should be freer? (Although we live in the freest country in the world!) 
For example, I feel limited by my body. I don’t mean that I have any kind of physical disabilities. But there are things I want to do and pursue, but my body is often too tired and weak that it affects my will-power. 
As an example, last night before I went to bed, I wanted to read this one article. But my eyes were too heavy and I fought against it for a little while only to wake up this morning with the iPad still by my head… 
There are times when I want to pray longer, but other thoughts and the pressing matters of the day will cloud the will-power and I will cut my prayers short. I want to meditate on the word longer, but I find myself dozing off and not being able to recall what I just read! And I find myself saying, “Wretch man that I am! Who will deliver me from this body of death?” (Romans 7:24)
Jesus understood all this. To the disciples who couldn’t stay awake to pray with Him on the last night before the cross, He says, “The spirit is willing, but the flesh is weak.” (Matthew 26:41)
How true that is! Over and over, I am reminded that my flesh is weak. Discipline will get you only so far. I may discipline my body to be a triathlon athlete, but I can’t control my tongue or stop my eyes from lusting.
But “thanks be to God through Jesus Christ our Lord!”  He has come to do what I can’t do. He has fought the good fight and won the victory for me! And now, I fight along side Him. Yes, I will take one or two steps back, but I will continue to fight my flesh and make it obedient (1 Cor. 9:27)
Keep fighting your sins. Rest in Jesus; not in your sins.
