How do we know that all who are saved will not be lost?

The sermon emphasizes that Jesus, as the Good Shepherd, guarantees the safety of His sheep. In John 6:37, Jesus states that 'all that the Father gives me will come to me, and whoever comes to me I will never cast out.' This assurance is rooted in the sovereign grace of God and the predestined purpose of Christ. The sermon articulates that salvation is ultimately not based on human action but on God’s eternal decree, assuring that all whom God has chosen will be saved. Therefore, none of those given to Christ will face eternal loss.
