 If our earthly fathers can keep a simple promise to cash a birthday check, can we depend on our Heavenly Father to keep His promise of the inheritance of eternal life? Will He remember to raise us up to the places He's prepared for us? Absolutely, yes. He will remember, and He's already given us the assurance of this inheritance. In the Ephesians 1 text, we read that He sealed us with the promised Holy Spirit, who is the guarantee of our inheritance.
