How is God's sovereignty evident in salvation?

God's sovereignty extends to the realm of salvation, asserting that it is entirely a work of His grace. This is evident in John 3:27, which emphasizes that nothing can be received unless granted by divine authority. This idea is further articulated in Romans 9:15, reminding us that God chooses whom He will extend mercy to, highlighting that salvation is not based on human effort but solely on God's sovereign will. Consequently, this understanding reassures believers that their salvation rests securely in God's hands, devoid of any reliance on personal merit.
