How can we know who is part of God's chosen people?

The identification of God’s chosen people unfolds through the preaching of the gospel. As articulated in Mark 16:15, believers are called to proclaim the gospel to every creature, and those who respond with faith demonstrate that they are among the elect. This process of coming to faith is sovereignly governed by God, who opens the hearts of individuals to embrace His mercy and grace as revealed in Jesus Christ. Consequently, the preaching of the gospel is both a call to outreach and a revelation of God’s electing love.
