Our Guaranteed Inheritance

In Ephesians 1:14, the Apostle Paul underscores the Christian's assurance of his eternal inheritance by showing that the seal of the Holy Spirit, which marks God's people as His special possession, is also their "guarantee" of inheritance. This "guarantee" is the the first installment, identifying His people as those selected for adoption. As His legal sons (through Christ's work of redemption), they are "guaranteed" the inheritance.
