How does God's purpose relate to His promise of salvation?

God's purpose is intrinsically linked to His promise of salvation, forming the foundation upon which redemption is offered to His elect. The Scriptures affirm that all whom God saves are chosen by His eternal decree (2 Peter 1:4). This purpose ensures that God's promises are not merely hopeful aspirations but guaranteed realities. In Romans 3:24, Paul teaches that we are justified freely by God's grace through the redemption in Christ Jesus, highlighting that our justification is secured by God's immutable purpose. Therefore, the promise of salvation is not contingent upon human effort but firmly rests in God's sovereign will and eternal plan, ensuring that all whom He has called will be saved.
