A good overview of why a Sabbath rest is important. It covers scriptures, blessings for keeping the Sabbath as well as reasons we may prevent ourselves from entering God's rest.
It's an easy-to-read book. It quotes Hebrews, John and a few Old Testament references on why we need a Sabbath rest. Pages 190-191 list reasons people miss God's rest such as unbelief, striving, lack of diligence and dead works. It stresses that Sabbath rest is about life, not law (PG 104). The Sabbath is there to rejuvenate us.
The author states in chapter 3 that we all have 4 tanks that need to be filled. He says our spiritual tank is filled by the Lord's strength, our physical tank is filled by rest, our emotional tank is filled by joy, and our mental tank is filled by focusing on God as in Philippians 4: 6-7. I agree, but would add that our spiritual needs are satisfied by God's presence and refreshment (PG 128-129). We need the Sabbath so we reconnect with God and don't forget about Him. Our physical needs also include sleep. Our emotional needs include lamenting or crying out to God about our lives, and our mental needs include trusting God as in Psalm 46:10. We must focus on God and believe in who He is as well as believe what He says.
I think this is a good reminder to Christians about the Sabbath, but I'm not sure it is for Jewish believers. They'll find good words in this book, but not a Hebraic perspective. The Sabbath is one of the 10 commandments, and it's a perpetual covenant. The commandment states that the Sabbath is on the 7th day of the Lord. It's holy. I used to believe that the day didn't matter. But when God told me to follow Saturday Sabbath, my blessings increased.
The final chapters give instructions on what to do on Sabbath to find rest (PG 202-203). Be quiet and wait on God silently as in Psalm 62:1. Focus and turn to God. Remind yourself of His goodness. Talk to God and bring your concerns to Him as Philippians 4:6 says. Listen for God to speak to you and renew your mind. Renewing your mind is replacing false ideas with truth (PG 210). Let the Spirit of God guide you into truth and tell you God's thoughts and what's to come (John 16:13-14). Put God first and you'll live life with abundance, peace, joy, power, satisfaction, and fruit. These come from being with God, being His branch as spoken of in John 15. Don't be distracted from spending time with God. Good instructions and advice.
