Let God Test Your Heart (Psalm 7:9)

Oh, let the evil of the wicked come to an end, and may you establish the righteous—you who test the minds and hearts, O righteous God!

Psalm 7:9

The elements in this verse should serve as frequent prayers for those who love the Lord. We will explore three ways to pray like David:

First, we should pray: let the evil of the wicked come to an end. In the Hebrew the request is more emphatic: “please let it cease!” David’s enemies were close around his neck; at any point those who disregarded God might have their way with his life. While we may never cross such direct evil or threats against our lives, there has always existed in man’s hearts a rebellion against those who seek after the Lord. Christ himself was no stranger to this evil. But what did he do in the face of his persecutors, the ones who sent him to the cross? He “did not revile in return; when he suffered, he did not threaten” (1 Pt 2:23). Are you tempted to enact revenge for yourself today? Like David you must entrust the evil in the world to the justice of God: Oh Lord, only You can make it cease once for all! But please, we pray, Your kingdom come!

Second, we should pray: God, may you establish the righteous! For David, righteousness meant a heart which sought the Lord and kept its way blameless—not necessarily perfect, but nonetheless sincere. Such an attitude of God-seekers can be found in Psalm 27:4: “One thing have I asked of the LORD, that will I seek after: that I may dwell in the house of the LORD all the days of my life…” Oh, how this prayer should be ours! God, establish in me a heart purely devoted to pursuing you. Keep me blameless in my love; rid my heart of any blemish which threatens a sincere and pure devotion to Christ! And when we fail in this regard, as those who stand on the other side of the cross and empty tomb, we trust that Christ’s perfect life has been accounted to us as righteousness. Oh God, establish more of your people who will seek and honor you in righteousness!

Lastly, we should pray for God to test our minds and hearts. This dual phrase “mind and heart” means the deepest parts of our being, the places where no one else can go but God. Therefore praying this last prayer will truly discern whether we are in the first category (the wicked), or the second (the righteous). To ask God to search your heart is indeed a frightful prayer—who knows what will be exposed? But it is necessary, for those who truly love Christ cannot stand their own sin; they need it exposed and eradicated by the cleansing power of the blood. Praise God the fountain is open and flowing full of grace!

Sadly, the wicked alway seek to hide their sin as one who obscures his deeds in the late hours of the night. As Paul says, “it is shameful even to speak of the things that they do in secret” (Eph 5:11). Oh reader, please hear! God cannot be fooled. Either we run to the cross, bringing our darkness to light, knowing our sin separates us from a loving God yet Christ reconciles us; or we attempt to conceal it, standing under the judgment of a righteous God, avoiding the piercing eye of our Creator who calls all to account for everything said and done. Please do not be the latter. If there is sin in your heart today, let it be exposed.

I assure you, if you confess your sin, he is faithful and just to forgive you and cleanse you from all unrighteousness (1 Jn 1:9).
