Yet, the strength of those who wait with hope in the Lord will be renewed. They will soar on wings like eagles. They will run and won’t become weary. They will walk and won’t grow tired. [Isaiah 40:31 (GW)]

I’ve been known to protest to my trainer when he adds more weight as I exercise. Even knowing that I’ll never get any stronger without increasing the weight lifted, I grumble. Fortunately, I trust my trainer and know he’ll never give me more than I can handle. Moreover, he’s right there beside me, ready to help as I struggle with the last few reps. Pretty soon, I find I can manage on my own and, before I know it, the weight I struggled with becomes the weight I start with on my next set. To increase my endurance, rather than increase the weight, he makes me do more repetitions and extends the time I hold the weights.

In His infinite wisdom, God uses those same concepts to build strength and increase endurance in our spiritual lives. He doesn’t want spiritual weaklings; He wants spiritually strong men and women! When we think He’s given us too much to handle, we must trust that He’s there beside us, helping as we struggle with our load. When we wonder how much longer we can endure under the weight of our troubles, remember He knows our capabilities. God won’t ever give us more than we can handle for longer than we can hold it. He is, indeed, pumping us up!

If a man does not exercise his arm he develops no biceps muscle; and if a man does not exercise his soul, he acquires no muscle in his soul, no strength of character, no vigor of moral fiber, nor beauty of Spiritual growth. [Henry Drummond]

We can rejoice, too, when we run into problems and trials, for we know that they help us develop endurance. And endurance develops strength of character, and character strengthens our confident hope of salvation. And this hope will not lead to disappointment. For we know how dearly God loves us, because he has given us the Holy Spirit to fill our hearts with his love. [Romans 5:3-5 (NLT)]
