en·dur·ance n. The act, quality, or power of withstanding hardship or stress
When I think of endurance I always think of runners - those who keep on, even when every muscle in their body is saying STOP! I can't say I remember exactly what that's like - I was a runner in my younger days, but have lost the desire to be one now - but I do love those with endurance! I strive to be one with endurance.
The great thing for us as Christ-followers is that our "power" is coming from the one true, endless Source!
He never promised us that life would smooth-sailing, stress or hardship-free. He did, however, promise that He would be our source of never-ending strength - so that we can endure! And not just endure, but endure with gusto - endure victoriously!
