I love this:

11Here is a trustworthy saying: If we died with him, we will also live with him; 12if we endure, we will also reign with him. If we disown him, he will also disown us; 13if we are faithless, he will remain faithful, for he cannot disown himself.

If we die with Him-
I take this as putting away our selfish desires that lead us away from Him-dying to sin
We will also live with Him-
Then we will experience true life in the Presence of the Living GOD!
If we endure-
This life is hard, esspecially when we are trying to follow GOD, but if we do without giving up
We will also reign with Him-
Yippie!!!
If we disown Him-
I think this means in speach and actions. By doing something that GOD said not to do is like
saying I dont know Him. maybe. not sure haha
He will also disown us-
"I tell you the truth, I never knew you."
If we are faithless-
We have slumps, slack off in our devos, feel like giving up
He will remain faithful-
No matter what we do, He is still faithful!!! I can't get over how amazing that is!!! What a
GOD we worship!!! Afterall, we were still faithless when He died for us.

Thanks be to GOD
