How do we know God's call is irresistible?

The concept of God’s irresistible call is reflected in the covenant promises in Isaiah 55. This call is distinguished from the general call of the gospel and is aimed specifically at God's elect. As seen in Isaiah 55:1-3, those who are spiritually thirsty are compelled to come to Christ, the water of life, through the gracious work of the Holy Spirit. The pastor highlights how this call transcends mere invitation; it is an effectual summons that brings about a desired response, drawing believers into a covenant relationship with God, guaranteed by the atoning sacrifice of Jesus Christ.
