How does the new covenant relate to the assurance of salvation?

The new covenant outlined in Jeremiah 31 reinforces the assurance of salvation by establishing God's irrevocable promise to forgive the iniquities of His people. In verses 33-34, God declares that He will make His law internal, allowing His followers to truly know Him and experience His forgiveness. This internalization signifies a transformative relationship with God, where believers are empowered by the Holy Spirit to walk in His ways. In confirming this by Christ's sacrifice, found in Hebrews 10:19-22, believers are invited to draw near to God with confidence, solidifying the promise that salvation is secure in Christ's completed work, independent of human effort.
