The puritans used to describe the Gospel as a multifaceted diamond. Like a diamond, the Gospel has many sides that create a new glimmer or sparkle with the slightest rotation in any direction. We associate diamonds with beauty so that we stare at them, study them, and admire them. The Gospel should be treated the same way (but to a much greater degree), but too often we act as if the Gospel is just the ticket that gets us into the club called “Christianity” and then the ticket is left with the guy working the entrance. The Gospel is more than a message for the conversion of unbelievers, it’s a message that gives reason and motivation for living a life of worship to God through the many decisions we face from day to day.
An example of this can be seen in 1 Corinthians 15. Here, Paul spends the entire chapter detailing the essential importance of Jesus’ resurrection (one of the Gospel’s many facets) for the hope of the believer. Then, in the very last verse of the chapter, Paul writes, “Therefore, be steadfast, immovable, always abounding in the work of the Lord, knowing that in the Lord your labor is not in vain” (v. 58). Paul is taking one side of the Gospel (the resurrection) and using it to motivate believers to increase in the Lord’s work. He’s not writing to people who need to be converted, he’s writing to a church of believers who need to be influenced toward godly living, and he’s using the Gospel to get them there.
When a woman is given a diamond engagement ring, she doesn’t scream, cry, giggle and then put the ring back in the box. She puts it on her finger, examines it, looks at it from every angle, delights in its beauty, and keeps it on her finger to remind her of her fiancée’s love so that she will continue to love him in return. This is what the Gospel should be like for every believer: let’s study the Gospel from all its angles, delight in its beauty, and keep it with us to be reminded of God’s love for us so that we will return that love in passionate, committed obedience.
