Scripture reading:      Psalm 139
Scripture text:            Psalm 139: 23, 24; Catechism Lord’s Day 44

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. (Psalms 139:23-24 NIV)

The author of Psalm 139 discovered the omnipotence and omnipresence of God the Lord.
And then the disturbing thought: The Lord sees through him!
Now he actually invites the Lord to search his mind. He trembles before the Lord, but he wants to expose his mind to the Lord. He wishes to be tested and purified by God, and then to receive forgiveness for his sin from the Lord:
The truly faithful can do this, because he knows that the Lord will discover all his sinful desires – but this is exactly what he wants to get rid of.

All my longings lie open before you, O Lord; my sighing is not hidden from you. (Psalms 38:9 NIV)

Normally man’s desires are not really commendable before the Lord. Just consider what is said in Psalm 140:8:

do not grant the wicked their desires, O Lord; do not let their plans succeed, or they will become proud. Selah (Psalms 140:8 NIV)

The Holy Spirit indeed warns us that our desires form part of totally unsavoury things. Listen to Colossians 3:5:

Put to death, therefore, whatever belongs to your earthly nature: sexual immorality, impurity, lust, evil desires and greed, which is idolatry. (Colossians 3:5 NIV)

The Lord tells us that we, as the elect, should detach ourselves physically and spiritually from all evil – among others we should break away from lust:

Dear friends, I urge you, as aliens and strangers in the world, to abstain from sinful desires, which war against your soul. (1 Peter 2:11 NIV)

In the language of the Old Testament this poet is repenting of his sins before the Lord.
This is exactly what every one of us should realise before we can proceed in our faith (Catechism Lord’s Day 44).
Of course this is not so easy, because we know our sins and misery from the law of God, and when we deal with the law we have great problems. Just consider what Paul says about it in Romans 7:7:

What shall we say, then? Is the law sin? Certainly not! Indeed I would not have known what sin was except through the law. For I would not have known what coveting really was if the law had not said, “Do not covet.”

In essence all sins originate from not keeping the tenth commandment, because we cannot sin unless we have the desire to sin. This underlines the difficulty of the law.
Now we also believe – based on what the Bible teaches us – that we cannot just ignore or reject the law:
All of a sudden this is no longer such a simple matter, because look at our lives!
Fact is that we have the desire to trespass almost all the commandments. But it does not stop there – we often do what we desire. This affects all the commandments of the Lord.
When we are honest we are ashamed of ourselves, because it’s not true that we have no desire to sin against the Lord.
Our struggle against sin does not always appear very vigorous, because we are plodding on like the Israelites in the desert – on the same level.
It’s true that we are often guilty before the Lord because we trespass against his commandments.
Let’s apply this entire matter to ourselves. When we look at ourselves we realise how weak we are and unable to keep the law. But the Lord is merciful. The Lord’s grace is more than enough, because it comprises the gospel of Christ.

1 John 1:8-9 teaches us the following:

If we claim to be without sin, we deceive ourselves and the truth is not in us. If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness.

When we realise what sin is and we listen to the guidance of the Holy Spirit, then new desires start developing in our hearts.
Now, do not lose faith.
The Holy Spirit ensures us that God has more than enough grace for us.
This brings us to another problem: If the Lord’s grace is sufficient then, why do we still preach the law and have to keep it?
This is why the law must be preached.
The law teaches us what we receive through Christ.
Then, inevitably, we reach a situation where we:
Let’s press on toward the things we may desire – holiness and worshipping God. Let us strive to live a good life up to the day we exchange this life with the eternal life without sins with God.

Let’s read together Catechism Lord’s Day 44.

113. Q. What does the tenth commandment require of us?
A. That not even the slightest thought or desire contrary to any of God's commandments should ever arise in our heart. Rather, we should always hate all sin with all our heart, and delight in all righteousness.[1]
[1] Ps. 19:7-14; 139:23, 24; Rom. 7:7, 8.

114. Q. But can those converted to God keep these commandments perfectly?
A. No. In this life even the holiest have only a small beginning of this obedience.[1] Nevertheless, with earnest purpose they do begin to live not only according to some but to all the commandments of God.[2]
[1] Eccles. 7:20; Rom. 7:14, 15; I Cor. 13:9; I John 1:8. [2] Ps. 1:1, 2; Rom. 7:22-25; Phil. 3:12-16.

115. Q. If in this life no one can keep the ten commandments perfectly, why does God have them preached so strictly?
A. First, that throughout our life we may more and more become aware of our sinful nature, and therefore seek more eagerly the forgiveness of sins and righteousness in Christ.[1] Second, that we may be zealous for good deeds and constantly pray to God for the grace of the Holy Spirit, that He may more and more renew us after God's image, until after this life we reach the goal of perfection.[2]
[1] Ps. 32:5; Rom. 3:19-26; 7:7, 24, 25; I John 1:9. [2] I Cor. 9:24; Phil. 3:12-14; I John 3:1-3.

Amen.
