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.
Since Christ’s priesthood continues forever (He 7:24) He can do something that no other priest could do. This is the implication of Christ’s eternal priesthood.
He is also able
The word “able” means Jesus can do what He promises to do. Note what our Lord is “able” to deliver Christians on a continual basis. This word is used for comforting believers (He 2:18), sympathizing with believers (He 4:15) and here of delivering Christians.
God has the ability to work on behalf of the Christian day-by-day.
Note passages that deal with God’s ability in relation to Christians: able to build them up (Ac 20:32), make them stand (Ro 14:4), establish them (Ro 16:25), make grace abound toward them (2 Co 9:8), “able to do above all that we ask or think” (Eph 3:20), keep them (2 Ti 1:12), keep them from falling and present them faultless (Jude 24).
