What is life all about, anyway?

1 Peter 2:21
For God called you to do good, even if it means suffering, just as Christ suffered for you.

This verse stuck out to me when I read the Word this morning. I am currently struggling with the suffering I am encountering trying to do something God wants me to do. Its not a huge thing or anything. Just a small thing I feel the Lord is leading me to step out and do. Deep in my soul I know it is going to bless me, but then there is this other part that is leaving doubts in my mind. Of course, the doubts are not from God, but it is hard to shake them.
But according to this verse, God is calling me to do good, EVEN if it means I will suffer while doing it. For some weird reason that verse comforted me.
I am also reading Don't Waste Your Life by John Piper, and I found some inspiring words in there as well- " [Life] is about the greatness of God, not the significance of man." Wow. John Piper's words there just showed me that stepping out and doing things for the Lord that are uncomfortable is to bring glory to God. It gave me a new perspective. No longer am I going to step out and doing this thing that is going to bring me uncomfort, but I am stepping out and doing this thing that will bring God glory. Its really cool how my attitude changes once I take ME out of the picture. Once I take ME out of the picture and focus on GOD, I feel like I can do anything. It's like having a superpower. Oddly enough, I just realized those last two sentences as I wrote them. God is great. I feel if I keep focusing on Him, it will make me feel at least a little less uncomfortable about my situation.

I don't know what I would do without Him.
