How do we know that God saves believers on purpose?

In the narrative of the demoniac of Gadara, we see clear evidence of God's purposeful salvation. The preacher emphasizes that Jesus did not accidentally stumble upon this man; rather, He was sent on a mission to save him. This aligns with the doctrine of election, wherein God chooses His people intentionally, affirming that they are saved on purpose. The man was in desperate need because of his condition, and Jesus knew this before He even approached the shore. Such intentional acts confirm that God’s love and saving grace are not arbitrary but sovereignly chosen for His elect, illustrating the beautiful purpose behind divine redemption.
