What does the Bible say about Christ's sacrifice for the elect?

In the context of sovereign grace theology, it is essential to understand that Christ's sacrifice was both sufficient for all and efficient for the elect. This distinction underscores the belief that while His death has universal implications, its salvific power is applied only to those whom God has predestined. This is supported by passages such as Ephesians 1:4-5, which highlights God's choosing of the elect before the foundation of the world, and Romans 8:28-30, which discusses the purposeful calling and justification of those He foreknew. Such texts affirm that Christ's atonement was designed explicitly for His chosen ones, ensuring that their redemption is secure and guaranteed.
