Today God is in the light. He is an open God. What then should we do? We should walk in the light. This means we will see God and know God in the light. Today we do not know God by way of conjecture as those in the Old Testament did. Today God has spoken. There is no need to make conjectures anymore. Today God is already in the light. He has already revealed Himself in the gospel. If we walk in this revelation, the result is fellowship. There will be fellowship between Christians, and there will be fellowship with God.
Since we are participants in the gospel and since God is also a participant in the gospel, the blood of His Son Jesus cleanses us from all sin. If we truly know God in the gospel, we will see that the blood of His Son Jesus is continually and eternally cleansing us of all sin (1 John 1:9). In the original language, this verse says that the blood of Jesus His Son is continually cleansing us from all sin. The Bible never shows us that the blood of the Lord Jesus does a second cleansing work. It shows us that the blood of Jesus cleanses us all the time. There are no multiple cleansings. There is only the continual cleansing. The Bible never has the thought of multiple cleansings. The biblical truth is a continual cleansing.
The blood of the Son of God continually cleansing us from our sins is the work of the Advocate. The work of the cross is once for all. But the operation of His cleansing and His blood is continuous. The cross dealt with our sins and washed away our sins only once. But it is forever effective. Why is it forever effective? Why is it cleansing us continually? It is because His Son is presenting the accomplished work to God continually. It is not a re-cleansing, but a continual demonstration to God that He has died and that all the sins are dealt with already. Today He is continually cleansing away all of our sins. All our sins are included here. The effectiveness of His blood lasts forever because the Lord Jesus is our Advocate continually in heaven. His work as the Advocate is a continuation and extension of His work as the Savior. The work of the Savior happened only once, but it is continued in the work of the Advocate. This is God's side of the work.
