In Paradise, the tree of life was a sacrament of the eternal life, on condition of man’s own obedience. Since the covenant of works is broken by disobedience, both Paradise and the tree of life as a sacrament are destroyed. But the Lord Jesus Christ, the Surety of the Covenant of Grace, gives to the chosen ones eternal life, which is the matter the tree of life sealed. Therefore, the Lord Jesus is called by way of application – and not as the antitype – the Tree of Life.
