Rest similar to the seventh day, wherein "God did rest the seventh day from all his works" Hebrews 4:4. Jesus is also according us with the same rest, and by entering into that rest, we also will cease from all our "own works, as God did from his" Hebrews 4:10.
Under the Gospel dispensation,Christ has accorded us with Spiritual rest, rest from the burden of the law of Moses, and from all toil and labour for life, and salvation by works. We enjoy much inward peace of soul, notwithstanding the world's troubles and Satan's temptations. Such who believe the word or Gospel of Christ with the heart, and in truth, these enjoy this rest; they are kept in perfect peace, and have much spiritual ease and comfort: this character distinguishes them from the unbelieving Israelites of old, and from present hypocrites.
What are you supposed to do?
From day one believe the gospel, and hold on to the promise of entering into his rest, even eternal rest. "Let us therefore fear, lest, a promise being left us of entering into his rest, any of you should seem to come short of it" Hebrews 4:1.
It is us who believe that promise God said "they shall enter into my rest," who shall enter in. And the writer says, "Let us labour therefore to enter into that rest, lest any man fall after the same example of unbelief" Hebrews 4:11. He said, "Seeing then that we have a great high priest, that is passed into the heavens, Jesus the Son of God, let us hold fast our profession" Hebrews 4:14.
Our calling is a profession, and like any other profession you have to be loyal to your boss. Where it is said believe the gospel, it means mix that same word with faith, meaning develop theories from scripture to explain your life situations; events, interactions, and patterns. A theory is a proposed explanation of those patterns, so is faith in the word."For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart" Hebrews 4:12. Faith has different scales.
Anyway, "For we have not an high priest which cannot be touched with the feeling of our infirmities; but was in all points tempted like as we are, yet without sin" Hebrews 4:15.
Jesus the Son of God, is our high priest; "For in that he himself hath suffered being tempted, he is able to succour them that are tempted" Hebrews 2:18, and support them through into glory.
