O Lord, rebuke me not in your anger,
nor discipline me in your wrath.
2 Be gracious to me, O Lord, for I am languishing;
heal me, O Lord, for my bones are troubled.
3 My soul also is greatly troubled.
But you, O Lord—how long?
4 Turn, O Lord, deliver my life;
save me for the sake of your steadfast love.
5 For in death there is no remembrance of you;
in Sheol who will give you praise?
6 I am weary with my moaning;
every night I flood my bed with tears;
I drench my couch with my weeping.
7 My eye wastes away because of grief;
it grows weak because of all my foes. Psalm 6:1-7
What anguish and pain David is feeling. Is it because of personal enemies? Is it because of some physical illness? Could it be grief over the recognition of the depths of his sin? Could it in some way be a combination of all three?
The tears will not stop. The eyes ache from the constant flood of weeping and through it all God seems to be ignoring David’s plight, or at least taking His own sweet time responding to his lament. How long Lord? Maybe that is the worst part. How long Lord? Are you there Lord? Do you even hear Lord? Do you care? Even the lightest burden becomes a crushing weight when there is no hope of relief. Yet the weightiest of burdens becomes bearable with a hope set before us. Jesus, for the hope set before Him was able to endure the cosmic, crushing weight of the sin of humanity on the cross in addition to the abandonment He experienced in being forsaken by the Father for a time. Jesus endured the cross for the hope set before Him. That hope was the rescue of the lost, the restoration of the broken. I was that hope. You were that hope. Jesus endured the Cross because of the hope of my salvation. It is was allowed Him to press ahead. How much am I willing to endure for Jesus, my Hope?
