25 Therefore He is also able to save to the uttermost those who come to God through Him, since He always lives to make intercession for them.
The idea here is to keep on saving. Once He saves our soul, He will continue to deliver us from issues in the Christian life, from the power of sin.
to the uttermost [completely]
Not only is our salvation continuous but it is complete. The only other place where “uttermost” is used in the New Testament is Luke 13:11, where a woman could not completely stand up straight. This is a contrast to this context where Jesus can completely deal with anything that comes our way. He can deal with the sin in our lives, with our adversity, with any issue in our lives.
“Uttermost” means completely. The salvation our Lord provided was fully extensive; He put us in perfect conformity with God (He 5:9; 12:23). There is nothing wanting in His work. He saves completely, totally, and forever. Jesus’ priesthood is unlimited in scope.
those who come to [approach] God through Him,
The qualification of Christ’s saving work is for those who come to Him by faith (Jn 17:6, 9). The Greek word for “come to” occurs 7 times in Hebrews (He 4:16; 7:25; 10:1, 22; 11:6; 12:18,22). It is used of believers in their postconversion life.
since He always lives to make intercession for them.
The reason Jesus can save to the uttermost is that He lives forever. The continual life of Priest Jesus allows Him to deal with sins as they may come. Not only does the priesthood of Jesus relate to initial salvation but with the ongoing life of the believer; the believer has free and continuous access to God. His salvation is complete.
“Intercession” is to intervene for someone else. This is the function of an advocate (1 Jn 2:1).
God is able to deal completely with any trial a believer might face.
Jesus always prays for the believer in heaven, not that God is reluctant to hear His prayers. Christ’s intercession for the believer never stops. His saving capacity never ends. Our Lord represents us before the throne of God without end.
Jesus is not only the offering but the Priest who offers it. He paid for our sin and he intercedes for us day-by-day. This grace began with our salvation and continues throughout the Christian’s life (Ro 8:34). Jesus does not deal with our sin in a half-way measure. He goes beyond covering sin (atones) like Levitical priests but He eradicates it. He can save forever because He lives forever.
Because of His inviolable priesthood Christ is able to offer complete salvation. His salvation operates in the eternal sphere of which He is a part. His ability operates in the realm of the transcendent.
