How do we know that God's sovereignty includes saving faith?

The doctrine of God's sovereignty over salvation is affirmed throughout Scripture, particularly in passages like Ephesians 1:4-5, which highlight God's choice in election. God is not a man that He should lie (Numbers 23), indicating His immutable nature; He cannot fail to keep His promises. Saving faith is the result of God's initiative, as seen in His unchanging purpose to save His people through Christ. When we understand that our ability to believe comes from His grace, we see the profound nature of His sovereignty. This understanding reassures us that our salvation is secure because it rests upon God's will and not on our fluctuating faith.
