How do we know that Jesus is able to save?

Hebrews 7:25 assures us that Jesus is able to save completely those who come to God through Him, as He always lives to intercede for them. In Daniel 9:24, the prophecy states that the Messiah would finish transgression, put an end to sin, and make reconciliation for iniquity, which Jesus accomplished through His sacrificial death and resurrection. His ability to save is predicated on His fulfillment of God's redemptive plan, thus providing enduring hope for believers that His work is sufficient and complete.
