Tony Evans:
When God wants to reveal the real condition of your heart to empower you toward His plan for your future, He puts you in one of these kinds of trials. 

Trial, perseverance, tired, perspiration…
Isn’t there something about those first beads of sweat coming down your forehead that tell you – “Yes, your heart rate is up and you’re doing the right thing for your body.”? Isn’t there something about that pain you feel after you’ve shredded your pecs, biceps, triceps, legs, etc. that lets you know “more muscle is on the way”?
