The Kingdom of Heaven is like a software developer who established rules to live and work by. One developer’s rules are quoted below, in bold text. For his software, he set out eight rules, seven of which we shall apply to God’s Kingdom.
1. Consistency matters. The gospel has agreement among all its parts, for Christ is the way, the truth, and the life, John 14.6. There is uniformity within and it produces a uniform effect among all who hear and welcome the Lord.
2. Discoverability matters. For this reason the Lord put his eternal purpose in permanent form, in a book (we know it as the Bible) that can be translated, reproduced, and distributed widely. “For we do not write you anything other than what you can read and also understand. But I hope that you will understand completely” 2 Corinthians 1.13. “The reader should understand this” Mark 13.14 NIRV. As well, in every generation, he sends his people throughout the world to publish the news of reconciliation because of the Cross, 1 Peter 2.9.
3. Simplicity matters. Anyone should be able to hear and understand the gospel as well as practice it. Like a child’s toy that needs no complicated instruction manual, any person can take the gospel, enter the Kingdom, spread the word, and reach others. No special training is required. One can “comprehend with all the saints” Ephesians 3.18.
4. Ease of use matters even more. The gospel is impressive in its “foolishness” 1 Corinthians 1.18-31. It was not made for those who are clever or considered intelligent. Jesus praised the Father “because you have hidden these things from the wise and intelligent, and revealed them to little children. Yes, Father, for this was your gracious will” Luke 10.21. All are lost in sin; all need to be able to obey and proclaim the gospel with ease. When simplicity is lost, so is ease of use. The Bible is open to the beginner and challenging to mature saint.
5. Everything should just work. There is nothing impractical, idealistic, or theoretical about the Kingdom of God. The perfect church was made for imperfect people. The gospel was designed for real-time, real-life problems of people who deal with the world as it is. God did not give us philosophical speculations, but spiritual solutions that work in every case and every time.
6. But that doesn’t mean you shouldn’t be able to configure anything. The Kingdom message is adaptable to every culture and language. One need not speak Hebrew and Greek to be saved or to be able to serve. God is wise. He did not set specific hours on the first day of the week to meet. Paul became “all things to all people” 1 Corinthians 9.19-22. That is the perfect combination of eternal truth and “configurable” approach.
7. There must be only one way to do a thing. Jesus is the only Savior. “For there is one God and one intermediary between God and humanity, Christ Jesus, himself human, who gave himself as a ransom for all, revealing God’s purpose at his appointed time” 1 Timothy 2.5-6. To be saved, there are defined and clear steps: hearing and believing the Good News, deciding to leave sin to serve God, being immersed in water to receive spiritual cleansing, loving God’s family, and serving the Lord faithfully. Worship must be acceptable to God, as he defines it, Hebrews 12.28, because we worship in spirit and in truth, John 4.23-24. God gave us a model or pattern to follow, in order to be justified, Romans 6.17-18.
Software is imperfect. It doesn’t always work as promised, because humans produce it. The developer’s rules above are good ones for better programs.
The Kingdom of God is the Lord’s and the gospel works as promised, because the perfect and powerful Designer knows exactly what we need and how to develop his eternal plan for our complete and eternal redemption.
So [Jesus] is able to save completely those who come to God through him, Hebrews 7.25.
