What does the Bible say about God's ability?

Scripture, particularly in Romans 4, illustrates God's ability to fulfill His promises as evidenced by the faith of Abraham. Abraham believed that what God had promised, He was able to perform. This concept of God's ability extends throughout the Bible, assuring believers that God's sovereignty governs all things, confirming their faith in His authority and capability. For example, in 2 Timothy 1:12, Paul expresses confidence in God's ability to keep what has been committed to Him, underlining the assurance that true believers possess regarding God's overarching power.
