Hebrews 3:15

While it is said, To-day - You may see the necessity of perseverance from the saying, "Today, if ye will hear his voice," therefore harden not your hearts - do not neglect so great a salvation; hold fast what ye have obtained, and let no man take your crown. See on Hebrews 3:7-9 ; (note) and Hebrews 3:12 ; (note).
