The document discusses the great things that God has done according to the book of Ephesians. It covers four key areas:
1) God settled our largest debt through Christ's sacrifice on the cross.
2) God satisfied our deepest need for forgiveness by forgiving our sins through Christ's death.
3) God provided our greatest desire for guidance by revealing the mystery of Christ and providing direction for how Christians should walk.
4) God prepared our highest longing by preparing an eternal home for believers in heaven.
The document encourages giving God glory for these blessings and making the decision to live for Him who died and rose again.
