How do we know that Christ saves to the uttermost?

The assurance that Christ saves to the uttermost is rooted in His eternal priesthood, which guarantees that He is able to save completely those who draw near to God through Him. This is reflected in scripture, demonstrating His role as our intercessor who is always active on our behalf. Unlike a priesthood that is temporary, Christ's priesthood is unchangeable; therefore, all who are given to Him by the Father will not be lost. This supreme confidence comes from knowing that He triumphantly accomplished our salvation, fulfilling the divine purpose of redemption at the cross and confirming His power over sin and death through His resurrection.
