The Word Of God Is Sharper Than Any Two Edge Sword.

Therefore, since a promise remains of entering His rest, let us fear lest any of you seem to have come short of it. For we who have believed do enter that rest, as He has said: “So I swore in My wrath, ‘They shall not enter My rest,’ ” although the works were finished from the foundation of the world. For He has spoken in a certain place of the seventh day in this way: “And God rested on the seventh day from all His works”; Since therefore it remains that some must enter it, and those to whom it was first preached did not enter because of disobedience, again He designates a certain day, saying in David, “Today,” after such a long time, as it has been said: “Today, if you will hear His voice, Do not harden your hearts.” For if Joshua had given them rest, then He would not afterward have spoken of another day. There remains therefore a rest for the people of God. For the word of God is  living and powerful, and sharper than any two-edged sword, piercing even to the division of soul and spirit, and of joints and marrow, and is a discerner of the thoughts and intents of the heart. And there is no creature hidden from His sight, but all things are  naked and open to the eyes of Him to whom we must give account. Let us therefore come boldly to the throne of grace, that we may obtain mercy and find grace to help in time of need.
