What does the blood of Christ do for believers?

The blood of Christ serves multiple critical functions for believers. First, it cleanses us from all sin, as stated in 1 John 1:7, and this cleansing is positioned as a continuous action. The 'ETH' suffix used in the text suggests a perpetual state of cleansing. As believers, while we continue to sin, we have the assurance that Christ's sacrifice provides an unending source of purification. It grants us fellowship with God, purges our conscience, and provides triumph over sin and Satan, enabling believers to live in the freedom of grace.
