Hebrews.
Chapter 4.
Therefore, while the promise of entering His rest still stands, let us be careful that none of you be deemed to have fallen short of it. 
For we also received the good news just as they did; but the message they heard was of no value to them, since they did not share the faith of those who comprehended it. 
Now we who have believed enter that rest. As for the others, it is just as God has said: “So I swore on oath in My anger, ‘They shall never enter My rest.’” And yet His works have been finished since the foundation of the world. 
For somewhere He has spoken about the seventh day in this manner: “And on the seventh day God rested from all His works.” 
And again, as He says in the passage above: “They shall never enter My rest.” 
Since, then, it remains for some to enter His rest, and since those who formerly heard the good news did not enter because of their disobedience, 
God again designated a certain day as “Today,” when a long time later He spoke through David as was just stated: “Today, if you hear His voice, do not harden your hearts.” 
For if Joshua had given them rest, God would not have spoken later about another day. 
There remains, then, a Sabbath rest for the people of God. 
For whoever enters God’s rest also rests from his own work, just as God did from His. 
Let us, therefore, make every effort to enter that rest, so that no one will fall by following the same pattern of disobedience. 
For the word of God is living and active. Sharper than any double-edged sword, it pierces even to dividing soul and spirit, joints and marrow. It judges the thoughts and intentions of the heart. 
Nothing in all creation is hidden from God’s sight; everything is uncovered and exposed before the eyes of Him to whom we must give account. 
Therefore, since we have a great high priest who has passed through the heavens, Jesus the Son of God, let us hold firmly to what we profess. 
For we do not have a high priest who is unable to sympathize with our weaknesses, but we have one who was tempted in every way that we are, yet was without sin. 
Let us then approach the throne of grace with confidence, so that we may receive mercy and find grace to help us in our time of need.
