Hebrews 6:11-15

11And we desire that each one of you may shew the same diligence unto the fulness of hope even to the end:

12that ye be not sluggish, but imitators of them who through faith and patience inherit the promises.

13For when God made promise to Abraham, since he could swear by none greater, he sware by himself,

14saying, Surely blessing I will bless thee, and multiplying I will multiply thee.

15And thus, having patiently endured, he obtained the promise.
