Romans 8:23-24

A quote from last Sunday's Bible class, regarding the burden of living with the sinful flesh, and the problem of trying to overcome sin:

We ourselves groan within ourselves, eagerly waiting for the adoption, the redemption of our body.
If you're longing for a time in this life in which you will not have a struggle with sin, you have your longing misplaced. And if you believe that, that's where the devil tries to rob you of your salvation. He wants you to try to find that place where you can say, "I am now finally no longer having any struggle." Oh no. That's dangerous.

For we were saved in this hope, but hope that is seen is not hope: for why does one still hope for what he sees?
So if you feel your sin, and you struggle against it, and you long to be free of it, God be praised. That's what it is to be a Christian in this life. "But I don't want to struggle!" you say; "I don't want to keep sinning." I know you don't. So confess your sin, believe the Gospel, and don't get too attached to the things of this world -- look up for your redemption draws near. "But I want the freedom from sin now!" you say. I know you want it now. But remember that the present sufferings of this life are not worthy to be compared with the glory which shall be revealed in you. And just as the suffering of Jesus was necessary on the way to His resurrection, so we who are baptized into Christ Jesus' death and resurrection must suffer until the glorious day of our resurrection. Do not be afraid: His proclamation is steadfast and unmovable.
