Why is knowing Christ important for assurance of salvation?

Knowing Christ is the foundation of assurance of salvation because it shifts the focus from our own deeds to His perfect work. Assurance stems not from knowing doctrines or having moral integrity but from a true relationship with the Savior. When believers genuinely know Christ, they understand that salvation relies solely on His righteousness and grace, which are unchanging. This knowledge fosters a deep-rooted confidence, as it assures us that we are secure in Him, who has accomplished all necessary for our salvation. Thus, assurance is intimately connected to our relationship with Christ rather than personal achievements.
