Why is the concept of being called important for Christians?

According to the sermon, the concept of being 'called' is of great importance for Christians because it denotes an effectual call from God that invites believers into fellowship with Him. Jude 1 emphasizes that those addressed are 'called,' which underlines the belief that God actively invites and draws individuals to Himself. This calling is not general but particular, ensuring that those who are chosen respond in faith. Scripturally, the call is tied intricately to the work of the Holy Spirit, which enables and assures believers of their salvation. It assures Christians of their identity as God's people and gives them the confidence to live out their faith.
