How can we be sure that we are part of those for whom the Son was given?

To ascertain whether we are among those for whom the Son was delivered, one must examine their relationship with Christ. Romans 8:16 states, 'The Spirit itself beareth witness with our spirit, that we are the children of God.' A genuine connection to Christ indicates that one possesses the Holy Spirit, who assures believers of their sonship. Furthermore, if a person genuinely seeks God's mercy, exhibits faith in Christ, and produces the fruits of the Spirit, these are signs of being in Christ. It is ultimately the work of the Holy Spirit that brings an individual to faith and provides assurance of belonging to God's elect, confirming that Christ was indeed given for them.
