Psalm 23 is a favorite of so many people. It is most often read at funerals, but the psalm is really for the living... for those who are journeying through a dark and sometimes lonely world. The glory of the psalm is that we do not walk through this "valley of the shadow of death" alone, for HE, the living and all powerful God of the universe is with us.
Because He is with us, v. 5-6 tell us that there is a banquet spread for us before those foes that sought to vanquish us. Ours is the final victory. In that "spread" that is laid out before us, we are told that "surely goodness and mercy shall follow us all the days of our lives..."
The word I want to home in on is "surely"... it is the Hebrew word ak, and can be translated surely, truly, or nevertheless. The translation i prefer is "only".... In other words this is the Rom 8:28 of the Old Testament. There are things that really look and feel bad in this journey through the valley of the shadow of death, but in that day, when we sit at the feast with our Lord Jesus and celebrate His and our victory, we will look back at all those bad and fearful things that we experienced and see ONLY the GOOD that our Father was working into our lives... and they will be bad and fearful to us no more....
But for God... this would not be true.
