We know God is able to save because of His promises in Scripture and His sovereignty in executing His will in redemption.
The ability of God to save is grounded in His sovereign power, as indicated in various Scripture passages. In 2 Timothy 1:12, we see that true saving faith is persuaded of God's ability to keep and save those who commit their souls to Him. This is further emphasized in Romans 4:21, where it states that God is able to perform what He has promised. Scripture consistently attests to the fact that God's will cannot be thwarted; He saves to the uttermost those who come to Him through Christ, as indicated in Hebrews 7:25. Therefore, the foundation of our assurance in God's ability to save is firmly rooted in His character and sovereign promise.
