What does the Bible say about God's power and ability to save?

Scripture illustrates that God's omnipotent hand is never reduced in strength; as stated in Numbers 11:23, God poses the question, 'Is the Lord's hand waxed short?' This rhetorical question underscores that there is nothing too hard for the Lord. His ability to save is rooted in His sovereign will and purpose, demonstrating that He does not depend on man's efforts or decisions. As Romans 4:21 declares, God is fully able to perform what He has promised, reinforcing the assurance that salvation is entirely His work.
