How do we know that Christ is our assurance?

Christ serves as the ultimate assurance for believers through His continual intercession and the work of the Holy Spirit. Throughout Scripture, especially in Hebrews 10:19-22, we see that our access to God and our confidence to approach Him is directly tied to Jesus' sacrifice and high priestly role. He carries our burdens and leads us to the assurance that, because He lives, we also live (John 14:19). His resurrected life reassures us that we are complete in Him, and relies on His promise to never leave or forsake us. This ongoing relationship through faith ensures that our assurance is firmly placed in Him alone.
