“Search me, O God, and know my heart,” is a prayer that should rise out of every sincere heart. There are several possibilities of this prayer.
One, there might be hidden sins in our hearts that only God’s penetrating search lights can reveal. It will give us a chance to confess and renounce them and find God’s mercy.
Two, there can be worries and anxieties in our heart which shows lack of trust in God, our Heavenly Father. When God’s search brings them out, it gives us a chance to ask God to give us grace to believe in his goodness and care towards us.
Three, there can be burdens which weigh heavily in our hearts. They sap our strength and kill our joy. The searchlights of God will spotlight them. Then we get a chance to pray to God to carry those burdens for us, which he does daily for those who love him.
Therefore “Search me, O God, and know my heart,” is a prayer that requires honesty as well as courage. It demands a willingness to change and also take action. It also shows trust in God who knows all about us—all our innermost secrets, fears, worries and hopes.
So let us too pray in the words of the Psalmist David,
“Search me, O God, and know my heart;
test me and know my anxious thoughts.
See if there is any offensive way in me,
and lead me in the way everlasting.”
— Psalm 139:23–24 Bible NIV 1984.
