The famous verse at the end of Isaiah 40 says, “…but they who wait for the Lord shall renew their strength; they shall mount up with wings like eagles; they shall run and not be weary; they shall walk and not faint.”
Too often we read that and envision “waiting” on the Lord to be some sort of placid inertness. Far from it! This is an active, expectant waiting — that maintains a vigilant readiness, that flexes ones muscles for action while scanning the horizon. How else is one’s spiritual strength renewed, if not by an expectant engagement with the presence and/or the promises of God?
“Make use of your faith. This is the chief mystery of our spiritual life. Stir up your soul to talk with Christ. Consider the promises and privileges you enjoy. Think of them, roll them under your tongue, chew on them until you feel their sweetness in your soul.”
“Unstirred coals do not glow or give heat. The beauty of faith is its use. Don’t just have muscles, use them. Let a man diligently and thoroughly improve his faith and the joy it will bring to him will be great.”
