Like Job and Jeremiah, the writer of Psalm 73 wonders if there is any value to being “pure in heart.” This should not be understood as arrogance, the writer has done what he believes to be all that he can to approach God in the proper way. He claims to be both pure and innocent.
It is possible to see this as an extremely self-centered prayer – “Why was I pure? What did it profit me to behave this way throughout my life, if the end is to suffer in silence while the wicked prosper?” Derek Kidner described this psalm as “pathetically self-centered” (Psalms, 260). This is the attitude of the older brother in the prodigal son story, and it is possible it is a thought many of us have had, although we may not allow it to rise to the surface too often for fear of our response!
He knows if expresses his doubt, he will betray the “children of God.” This is perhaps a hint that the writer is in some sort of leadership role, others are looking to him for answers, how he expresses his doubts will have an effect on the children of God who come to him for spiritual guidance.
It is not wrong to wonder and question, it is wrong to cause others to sin. The writer is therefore struggling with his doubt that the covenant actually works, that being pure in heart has any value at all, and he is wondering seriously if it might not be a better idea to live a life of arrogant wickedness if there is not value to his purity.
The solution to the problem is found in worship: no understanding is found until “I entered the sanctuary of God….” This verse is the key turning point in the psalm. When the writer enters into worship, his perspective changes. Notice the contrast in verses 16-17. “When I tried to reason this thing out on my own, it was oppressive to me.”
This human attempt to understand God’s working in the world is radically changed when he entered into worship – he began to focus on God and God alone. In doing so, he saw his suffering and the prosperity of the wicked from a different angle altogether, but he also saw his own suffering from God’s viewpoint as well.
The fact that our writer enters into the temple to worship ought to be at least some confirmation that he does have a pure heart and innocent hands, since these are the requirement for approaching God’s holy hill (Ps. 24, again).
Genuine Worship is therefore critical to our understand of God and his relationship with the world.
