We travel through our life.
As a matter of fact, we start at birth, and motion takes us until the last breath.
We are foreigners in this world, and for those who have believed in God, and in a victoriously risen savior (Jesus), we carry a hope for a new—better—world, helping us to ease our journey, —especially during life's trials.
Trusting God will give us the strength we need to continue our travel through life, to keep moving forward, in the midst of, in spite of,— which I have repetitively experienced in my own journey, as an offspring of foreigners, a foreigner myself in other lands... as a foreigner in this life.
Isaiah 40:31 says something that took me some time to process and personally digest:
"But those who wait for the Lord [who expect, look for, and hope in Him] shall change and renew their strength and power; they shall lift their wings and mount up [close to God] as eagles [mount up to the sun]; they shall run and not be weary, they shall walk and not faint or become tired."
Here is a promise for the weary traveler: to be provided with all needed strength to continue the journey, when we set our hope in the One who can help us beyond our weaknesses and give us grace to go over the difficulties of the way.
I have found the literature of the Bible to be rich in promises, providing us with undryable wells where we can come and personally draw portions of hope for our thirsty and weary souls... God didn't promise a life free from challenges, but He relentlessly invites us to put our trust and full hope in Him; expressing about Himself to be a solid rock where we can stand and build upon, a solid floor where we can step onto—that won't crumble—, a source of strength for our life journey, because He knows we'll need it and He wanted us to know that it all is accessible, at our disposal...
