2. Forget not that the Holy Ghost puts it down as a special note of reprobates, “They call not upon the Lord, they call not upon God.” (Psal. xiv. 4; liii. 4.)  And when Eliphaz supposed that Job had cast off the fear of God, and that God had cast Job out of his favour, he chargeth him that he restrained prayer before God (Job xv. 4;) making that a sure note of the one, and a sufficient cause of the other.  On the other side, that God has promised that “whosoever shall call on his name shall be saved.” (Rom. x. 13.)  It is certain that he who makes no conscience of the duty of prayer, has no grace of the Holy Spirit in him, for the spirit of grace and of prayer are one (Zech. xii. 10:) and therefore grace and prayer go together. But he that can from a penitent heart morning and evening pray to God, it is sure that he has his measure of grace in this world, and he shall have his portion of glory in the life  which is to come.
