Hebrews 4:3; Hebrews 11:6

3 For we which have believed do enter into rest, as he said , As I have sworn in my wrath, if they shall enter into my rest: although the works were finished from the foundation of the world.
6 But without faith it is impossible to please him: for he that cometh to God must believe that he is , and that he is a rewarder of them that diligently seek him.
