What does it mean that God calls His people?

The concept of God's calling is crucial in Reformed theology, as demonstrated in 1 Corinthians 1:24, where it states that for those who are called, Christ is the power and wisdom of God. This call is not a general invitation; it is effectual and transformative, meaning that when God calls a person, it results in their salvation. The sermon contrasts this divine call with human attempts to seek God, asserting that a genuine call from God brings about a new heart and faith in Christ, leading to spiritual renewal.
