Title: Search Me, O God and Know My Heart!
By: Ps Isaac Yim

Psalm 139:23-24 (ESV)

“Search me, O God, and know my heart!
Try me and know my thoughts!
And see if there be any grievous way in me,
And lead me in the way everlasting!”

This Psalm is another famous prayer of David. If you notice, this prayer starts and ends with the same request to God

v1. O Lord, you have searched me and you have known me.
v23. Search me, O God, and know my heart! Try me and know my thoughts!

At a glance it is almost the same, but it is not. Back in verse 1, the purpose was to show how much interest God takes in David’s life. That is a wonderful, comforting truth. Now David is asking for something else. In verse 23, the purpose of the search was David asking God to reveal any hidden sins in his heart to him, “O God, search me and tell me the result”, and in verse 24. “See if there is any grievous or offensive way in me, and lead me in the way everlasting.”

Over the next two weeks I will undergo two medical tests. The purpose is to find out the real situation of my heart and the functions of my other organs. I hope these medical experts will be able to reveal to me if anything is wrong, and then I can take any appropriate steps to correct whatever is wrong. My real reason for such tests is to make sure there are no hidden harmful things lurking inside me. If there is, I hope I can deal with them before it becomes harmful to my health and endanger my life. I know many may feel this is rather morbid.

Why did David pray a prayer like this? In this prayer, David uses four verbs,

  1. Search me (v23)
  2. Test or examine me (v23)
  3. Reveal to me (v24)
  4. Lead me (v24)

Oh, how much I hope all of us would take time to meet our Spiritual Specialist, the Holy Spirit. We need Him to help us to do a periodical thorough heart examination, to see if there is anything grieving or causing Him sorrow.

All sins are harmful. Somehow hidden sin seems to be less harmful, or at least many of us think so, but David knew that sin is like a disease, and if you catch it in its early stages it is much easier to take care of it. But the longer it remains undetected, the more damage it causes.

David asked God to test his heart and his thoughts. David did not ask God to examine his actions or words. He understood sinful actions are just symptoms. The real cause is beneath, which is the heart. All sin originates in the heart – not 70% nor 99.9% but 100%.

We need to ask God to reveal to us our wrong attitudes, wrong perspectives, wrong desires, wrong priorities and many other kinds of hard-to-detect hidden sins.

“For out of the heart come evil thoughts, murder, adultery, sexual immorality, theft, false witness, slander.” ((Matthew 15:19)

In effect, David is asking God to continuously search his heart of any self-will, rebellious attitude or any form of disobedience that lie hidden in his heart. Holiness is a life-long process.

“But exhort one another every day, as long as it is called “today,” that none of you may be hardened by the deceitfulness of sin.” (Hebrews 3:13)

Prayer for today

Search me, O God. I know that my heart is not always pure and my ways are far from perfect. Search me, O God, for I need your purifying presence. Search me, O God, for I want you to set the course and lead me in the way everlasting!
In Jesus’ name I pray. Amen.


“23 神啊,求祢鉴察我,知道我的心思;试炼我,知道我的意念。
24 看在我里面有什么恶行没有,引导我走永生的道路。”





  1. 监察我(23节)
  2. 试炼我(23节)
  3. 向我透露(24节)
  4. 引导我(24节)

哦,我多希望我们大家愿意多花时间与我们的属灵专家— 圣灵见面。我们需要祂帮我们定期做心脏检查,看在我们里面有什么令圣灵担忧的。


大卫求上帝鉴察他的心和思想。大卫并没有求上帝鉴察他的行为或言语。他明白恶行只是症状。真正的原因在于内心。所有的罪恶都源于内心 — 不是70%或99.9%,而是100%。
