I was reading about a single person who, when getting discouraged, turns to the following passage:
"Whom have I in heaven but you? I desire you more than anything on earth. My health may fail, and my spirit may grow weak, but God remains the strength of my heart; he is mine forever." (Psalm 73:25-26)
It is such an encouragement to remember that God is always there with us in our single (but not solo) journey.
