I am actually amazed at how refreshed I feel in the mornings and how even in the afternoons, I am not all that bad off, though we’re all glad to see the day come to an end. I think we all need times of extra rest through more sleep (“sleeping in”) or times away on vacation when we do as little as possible, except to simply enjoy.
I think too that the Lord’s life sustains us even in our physical existence. Actually God’s breath is the source for all human life, in fact all life period.
In what we call the spiritual life, we need the life breath of the Holy Spirit. The disciples were certainly alive with physical life when the Lord breathed on them and said, “Receive the Holy Spirit.” I take it that we are those through faith who live in that blessing in and through Jesus. While we live in the Spirit, it does not necessarily follow that we walk or keep in step with the Spirit. That is something we have to work on. But all of this is a strength to us in our weakness.
At the end of Isaiah 40 we are encouraged with these words:
The Lord is the everlasting God,
the Creator of the ends of the earth.
He will not grow tired or weary,
and his understanding no one can fathom.
He gives strength to the weary
and increases the power of the weak.
Even youths grow tired and weary,
and young men stumble and fall;
but those who hope in the Lord
will renew their strength.
They will soar on wings like eagles;
they will run and not grow weary,
they will walk and not be faint.
This reminds me that I need to wait or hope in the Lord. That I need to keep looking to him no matter what. He is our strength, our song and our salvation.
