How do we know our inheritance in Christ is secure?

Our assurance of inheriting the kingdom rests upon the immutable character of God's promises. In 1 Peter 1:4, we learn that our inheritance is reserved in heaven, highlighting that it is not subject to decay or loss. This reservation is a reflection of God's power to keep what He has promised, affirming to believers that their salvation and inheritance are not something that can be earned or lost but are guaranteed by His grace.

Furthermore, the overarching narrative of Scripture supports this assurance, demonstrating that God's covenant with His people endures throughout generations. The safety of our inheritance also finds support in the doctrine of perseverance, holding that those who are truly in Christ will continue in faith and thus ultimately receive the fullness of their inheritance. This reinforces the logistic that our hope is anchored not in ourselves but in Christ, who is faithful to complete His work in us.
