What cannot be contested honestly is:
Hebrews 3:7-4:11 where in
4:7-11, as God rested from the work of creation, the believer ceases his efforts to gain salvation by his own works and rests in the finished work of Christ on the cross. (
Hebrews 4:10)
Canaan was God's
promised rest from their enemies (
Joshua 1:13;
Exodus 33:14;
Deuteronomy 12:9-10,
Deuteronomy 25:19) into which they refused to go (
Numbers 14), and which God swore an oath in his anger, "They shall never enter
my rest," (
Hebrews 3:11, 3:18,
4:3), which is his
full-time rest from his creation work (
Hebrews 4:3-4).
But there
still remains,
apart from Canaan's promised rest, a Sabbath rest for the people of God (
Hebrews 4:6-9).
The NT believer enters "another" (
Hebrews 4:8) Sabbath rest for the people of God (
Hebrews 4:9-11); i.e., God's own ("my,"
Hebrews 3:11, 4:1, 3, 5, 10) full-time (
Hebrews 4:3-4) rest, in the believer's full-time salvation rest by faith (
Hebrews 4:10-11).
Jesus is the
fulfillment of the Law (
Matthew 5:17),
including the Sabbath, in whom we rest
from our own work to save, and
in his work which saves.
Feel free to exegete
Hebrews 3:7-4:11, accounting for
1) Christian
Hebrews being instructed to
enter their Sabbath rest (4:1),
2) references to
Canaan (3:8-9, 15-18, 4:2, 6, 8) in relation to the Sabbath,
3) God's
full-time rest from his creation work (4:3-4) and
4)
another Sabbath rest of "Today" remaining for the people of God (4:7-9)
all in consistency with the passage.
