Hebrews 4:1; Hebrews 4:6-8

1 God’s promise of entering his rest still stands, so we ought to tremble with fear that some of you might fail to experience it.
6 So God’s rest is there for people to enter, but those who first heard this good news failed to enter because they disobeyed God. 7 So God set another time for entering his rest, and that time is today. God announced this through David much later in the words already quoted: “Today when you hear his voice, don’t harden your hearts.” 8 Now if Joshua had succeeded in giving them this rest, God would not have spoken about another day of rest still to come.
