How do we know our inheritance with the saints is secure?

According to Colossians 1:12-13, it is the Father's work that makes us meet to partake of the inheritance with the saints in light. This preparation signifies that salvation is not dependent on our merit but solely on God's grace. By recognizing that faith in Christ grants us this status, we understand that we are positioned for eternal life and fellowship with God based on His promises. The assurance of our inheritance lies in the transformative power of the gospel and the Father's call, confirming that true believers will never be lost but rather sustained in faith until they are presented before God.
