Spiritual Understanding

John 13:7
What I do thou knowest not now: but thou shalt know hereafter.
Peter didn’t understand why the Lord was washing his feet. He was teaching His disciples a spiritual lesson - not a physical one - and without the Spirit inside them they couldn’t understand. In a practical sense we often do not understand what the Lord is trying to teach us through a trial of some kind. But if we spend time in His presence in prayer - afterwards we’ll understand, and there will be blessing from it.
