David sometimes asserts his own righteousness and faithfulness as the basis for God to vindicate him and destroy evil men. For example, Psalm 26 begins,
Vindicate me, O LORD,
for I have walked in my integrity,
and I have trusted in the LORD without wavering …
I walk in your faithfulness.
I do not sit with men of false hood,
nor do I consort with hypocrites.
I hate the assembly of evildoers …
[Psalm 26:1, 3-5]
And if we thought David’s request for God to test and try his heart and mind were evidence that David sees sin in his own heart, we see that in context it is just the opposite. It is in the midst of the above verses (Psalm 26:1-5), that David challenges God to examine that he is righteous:
Prove me, O LORD, and try me;
test my heart and my mind.
For your steadfast love is before my eyes,
and I walk in your faithfulness.
[Psalm 26:2-3]
So, what does David mean in this week’s fighter verse? After all, it is directly after speaking against the wicked (Psalm 139:19-22), that he says,
Search me, O God, and know my heart!
Try me and know my thoughts!
[Psalm 139:23]
Does David claim sinless perfection?
The next verse is enlightening as we ask this question. For in it, David admits that there may be hidden sin in him:
And see if there be any grievous way in me,
and lead me in the way everlasting!
[Psalm 139:24]
In David’s mind then, it is right and fitting for him to admit real or potential sin (see also Psalms 19:12-14; 51:1-9). And, at the same time, it is consistent for him to claim his righteous living as the evidence that he is righteous.
This is the paradox of the gospel. It is “by grace you have been saved through faith … not a result of works, so that no one may boast” (Ephesians 2:8-9). And yet, what are we saved unto? And how do we know we are righteous in Christ? Ephesians continues, “For we are his workmanship, created in Christ Jesus for good works …” (verse 10; see also 1 John 2:3-6; 9-11; 3:6-10). And the rhythm of the truly righteous life in Christ is to ask God to seek out sin and repeatedly confess it to him:
If we confess our sins, he is faithful and just to forgive us our sins and to cleanse us from all unrighteousness.
[1 John 1:9]
