The way our monotony of eternity being resolved by God shows HE is smarter than the smartest

Some people choose to be true believers [altruistic] and others choose to be unbelievers [licentious] over which God has no control. But placing them when and where in the drama of life is in His control, and this reveals agility, astuteness, ingenuity, intelligence and wisdom of God making Him “smarter than the smartest.” (a)

Having all inhabitants on earth as believers may seem GOOD,
but it is likely that they will become monotonous later, and any amount of extra work God does to keep them cheerful will be in vain.

Having all inhabitants as two groups, believers and unbelievers is BETTER as it has many benefits [including keeping the former free of monotony—that too without any extra work from God] as shown below:

1.    God’s unconditional love is manifested as the unbelievers too are permitted to make use of all provisions made on earth for life’s enjoyment even though HE is able to collapse the existence of the licentious like any Service Providers do to their uncooperative clients. (b)

2.    This provides opportunity to the believers to imitate unconditional love of God which makes their life more and more light and cheerful.

3.    Ill-effects reaped by the choices of the licentious are like free lesson for the believers on what to avoid to better enjoy life and to be even more determined to be spiritual. (c) It is like having alcoholics who lose their wealth and health which inspires the observers to gain wealth and health by avoiding alcohol.

4.    This provides the basis for this drama of life to be wonderful which is beautifully summarized by Jesus’ friend John: “The world is passing away (parēgen), and the desire of it, but he who is doing the will of God, he remains (menó)—throughout the age (aiōna).” (d) One section of mankind comes and goes but others remain on earth forever giving God the title “King of Ages” who is also described to be “living and ruling for ages (aiōnas) and ages (aiōnas).” (e). Doers of God’s Will live through both the halves of each Age (through its high-quality 1st half and also through its low-quality 2nd half). In contrast, others “pass through” only low-quality 2nd half of each Age. They hate to come to its first-half as things of their delight are not available there. (f)

5.    This results in situation where New Age (like Heaven) and Old Age (like Hell) rotate on earth, like Day and Night. By the time the spiritual begin to feel monotonous, the licentious arrive to give free lesson for the spiritual on what to avoid to better enjoy life thus to be ever cheerful, thus giving no extra work to God. This is highlighted in the famous Parable of Wheat and Weeds (g) which is complete world history in symbolic short-story format.

Thus everything works out for the good—Believers benefit from unbelievers, and unbelievers can also benefit from believers if they want to.

Interestingly, this composition of mankind (few the altruistic + majority the licentious) resemble micro universe called atom [whose bulk area looks empty] and macro universe [whose “less than 5 percent” is only visible to us] (h)
