How do we know Jesus can save completely?

In Hebrews 7:25, it is noted that Jesus not only saves but continually intercedes for His people. This ongoing role as our mediator assures us that His saving power is not a one-time event but a continual act of grace. His ability to save is rooted in His eternal priesthood and the unchanging nature of His character. This means that in every situation, regardless of our shortcomings or trials, we can rely on His advocacy before the Father and His capacity to completely redeem us from sin.
