What does it mean that salvation is according to God's will?

When we say that salvation is according to God's will, we affirm that it is not based on anything we can do, but solely on God's sovereign choice to show mercy. This is explicitly stated in Romans 9, where Paul emphasizes that it is not of him who wills or runs, but God who shows mercy. This understanding leads to a deep assurance for Christians that their salvation is secure, rooted in God's eternal plan that cannot be altered by human actions or decisions. This glorifies God and highlights His sovereignty in all aspects of salvation.
