losing one's life

Okay, I know this is somewhat backdated but i guess i'm going to continue talking about the things i learnt over retreat.
Well, one big thing that was really bugging me during the retreat was this: What's to stop me from becoming exactly the same as before the retreat? Nothing. I could really still be as selfish as i was before the retreat, because i mean, I'm sinful and I can try really hard to not be selfish (and to not sin) but it's not going to work, because I am human and sinful. So, there's really nothing I can do to stop sinning. Instead, I look to the only One who had a good sound response to sin, Christ who died and rose again, kicking sin in the butt! So God's daily portion of grace, enough to last me through the day and Christ's resurrection power will give me hope against sin each new day. Hope that I will move towards Christlikeness daily. So don't focus on yesterday's failures or successes, know that each day is a new one with a new portion of grace awaiting us to face the new challenges of the day.

Another important lesson that i learnt over the past 2 days is this:
Matthew 16:25For whoever wants to save his life will lose it, but whoever loses his life for me will find it
On monday, first weekday after the retreat, I was fasting for my church prayer walk. I also did a bible study on John 15 and spent the day(or stray thoughts during the day) figuring out what God was trying to say when he told the disciples to abide in Him, not because i was trying to be Holy, but because i genuinely didn't know what he meant and i really wanted to know. So without sounding proud, it was a relatively un-selfish day. Surprisingly, i managed to find time to do all that needed to be done that day (yes, this despite barely touching work during the weekend because of the retreat), and even got to talk to my family and watch bits of 24.
Tuesday however was a selfish day. I was selfish. I basically planned my day out and knew what i had to do and when to do them. Of course, I didn't do so well, ended up sleeping later than i planned and not really finishing everything that I had to do, even though I had more time than the day before!
I have no idea where all that time went, and how even though i had less time, i managed to do more on Monday. It really just goes to show that God is a better planner than I ever will be.
So, because I know i'm going to need this again sometime during the semester when the tests come around, I'm going to say it again

For whoever wants to save his life will lose it but whoever loses his life for me will find it Matt 16:25
