“Jesus has become the guarantee of a better covenant” (Hebrews 7:22).
I work in the floral department of a grocery store and we have one particular arrangement that is guaranteed to stay fresh for 7 days, or your money back. In the retail industry a money-back guarantee is common. In fact, our store offers a money-back guarantee on anything you purchase. If you’re not happy with it, we will cheerfully refund the full purchase price. That’s okay for flowers or cheese or a can of beans, but sometimes the stakes are quite a bit higher. If the auto repair shop guarantees your new brakes or your money back, you may not be alive to collect on it should they fail.
God offers a perfect guarantee. He makes incredible promises and backs them up – not with a financial incentive, but with Himself. More than a thousand times in Scripture God says, “I will” and it comes with the assurance of His name and His character. He promises to never leave us nor forsake us. He promises to lead us, care for us, carry us, watch over us, protect us, provide for us, comfort us, and bless us. And most importantly, He promises to save us from our sins and give us eternal life. What is our guarantee for His promises? “Jesus has become the guarantee of a better covenant” (Hebrews 7:22). Jesus Christ is all the guarantee you need. And if that we’re enough for us He also gives us His Holy Spirit “who is a deposit guaranteeing our inheritance” (Ephesians 1:14). The Holy Spirit marks you as a child and heir of the God of the universe. Our Heavenly Father doesn’t have to offer a “money-back guarantee” because His promises will never fail.
