How is the faith of God's elect manifested?

In Titus 1:3, Paul indicates that God's promise is manifested through the preaching of His Word in due time. The faith of God's elect is activated and expressed when they hear the Gospel and believe its truth. This shows that God uses the means of preaching to call His chosen ones to faith. The proclamation of the Gospel serves as a catalyst for the faith that God has sovereignly granted. This underscores the importance of preaching in the life of the church as the method by which God reveals His saving truth to the elect.
