Wisdom from God through my Discipler Jordon:
Those who wait upon the Lord shall renew their strength.
They will soar on wings like eagles,
They will run and not be weary,
They will walk and not faint.
so in your discipleship...
wait upon means to serve/minister/take instruction/take heed/listening to God =D
notice the transition... Strength to Soar> Strength to run> and at last, strength just enough to walk...
and not just a stroll,
the verse describes that walk as the kind where you take it step by step forward relying on God so that you don't faint...
maybe, now's your walk with God..
it's not a flight, nor a run... as freely as before...but a walk...
and but be sure, God will give you enough strength to take that next step forward.
