The secret of the promise is the bearing of the curse so that the blessing may prevail. The gospel is that in Jesus Christ the curse has been set aside and God’s creative purpose for the blessing of his creation is established beyond any possibility of reversal.
God’s last and effective word is his blessing. It is a particular word spoken in the life, death and resurrection of Jesus, broadcast by those who like Paul cannot but pass it on, so powerful is its effect, over flowing with blessing from those who, blessed by it, become a blessing to others.
