How do we know that God's people will be gathered after death?

The assurance of being gathered after death is a promise for all those who have been converted by the gospel. Abraham, in Genesis 25:8, was gathered to his people, which signifies the gathering of the faithful into the presence of God. This gathering is not merely a physical burial but a spiritual union with other believers and ultimately with Christ, who is at the center of our hope. As seen in Colossians 2:10, believers are complete in Christ, which emphasizes that our fullness and gathering in the afterlife are found solely in Him, ensuring eternal communion with the family of God.
