10 For whoever keeps the whole law and yet stumbles at just one point is guilty of breaking all of it. 11 For he who said, “You shall not commit adultery,” also said, “You shall not murder.” If you do not commit adultery but do commit murder, you have become a lawbreaker. This is confusing to me. One breaks 1 law and we are held guilty for breaking all. Sounds unfair, but know there is a scripture answer that will help me understand.
The book of 1 John sheds a good light on our relationship with God's Law. He sums up the Law in loving God with all our heart and loving others as we love ourselves.
David says that he loves God's Law and he meditates in it day and night; while Paul says that we are not subject to the Law and that no one is justified by the Law.
What is important is that David had his heart toward God, and therefore loved His Law, even though we see that he did not keep it perfectly. Paul refers to those who seek to be justified by the outward observance of the Law as a set of strict rules in order to be accepted by God but without having their heart renewed.
Those who seek to please God by keeping the Law, find it a duty and a burden which if they could escape it they would.
But David knew that when he failed, he knew that he would be forgiven. He said, "There is forgiveness with You, that I might fear You." What this means is that knowing that he will not be condemned for his failures, meant that he could be free to genuinely fear the Lord and love Him and His Law.
This is the same with us. We know that as born again believers, there is no condemnation for us, even though we can't keep the Law perfectly. Paul says that the Law is spiritual, but we are sinful, and so it is not the fault of the Law that we can't keep it, it is our sinfulness that causes us to fail. This is why we have 1 John 1:9, that when we do fall off the wagon of holiness, we can go to God's throne of grace, confess our sin, and receive forgiveness and cleansing.
Because we are set free from condemnation through God's forgiveness through the shedding of Christ's blood, we can love God's Law and spend much time meditating in it day and night, and as we allow the Law to guide our lives, we become stronger in our faith and determination to serve the Lord the best we can.
David said, "I have hidden your Word (the Law) in my heart that I might not sin against you."
The Mosaic ceremonial Law was made up of symbols and figures that are fulfilled in the Gospel of Christ. But when David and Christ speak of God's Law, they are speaking of the written Scriptures which contain not only the Commandments, but the promises of God as well.
"sinning against you", means to reject God and Christ entirely.
We have the treasure in earthen vessels, and what motivates us to love the Lord and to fear Him, is that forgiveness is in His nature toward us as born again believers who have new hearts to love and serve Him.
