It's been long since I started exercising

I believe God is raising all of us into warriors
Warriors for the Kingdom of God
And I believe it is not myself that I just suddenly felt like exercising
I believe the Holy Spirit told me to go out there and run
And I'm reminded on how unfit I am
Even though I'm strong for my weight category
But it doesn't mean that I'm strong and fit
Without this daily training
How am I going to overcome more obstacles in the nearing future?
God will no doubt test me, and I must be ready
And, I'm very sure of what obstacles are coming next.
