What is God's role in our salvation according to the sermon?

In the sermon, it is emphasized that it is ultimately God's sovereign will that determines who receives salvation. John 1:12 states that 'as many as received him, to them gave he power to become the sons of God,' highlighting that it is God's divine enablement that allows individuals to embrace Christ. This underscores the concept of irresistible grace found in Reformed theology, wherein God creates a longing within the hearts of the elect, leading them to repentance and faith in Christ, thus ensuring their salvation.
