I inadvertently played Captain Sensible and Yoko Ono at the same time; occasionally the dreadful guitar and the awful screeching were on the same note – but neither of them seemed happy. South Pacific is not a film I'll ever watch (Paul Gauguin's depictions of the region are more than enough for one lifetime) but imagine things from the young persons' point of view: to have Humpty-Dumpty leering at your every interaction from two feet away† is very unlikely to produce happiness.
So often we hear God's message through the ages mocked, derided as utterly divorced from reality. By that is meant aspects of reality we can actually confirm and by
divorced, is meant that if God is so out of touch with what we can see for ourselves, how much worse will He be concerning the rest? Mockery and derision is bad enough but sometimes our opponents get physical, running us through with spikes or burning us alive. For centuries this has gone on, not at all times in all places, but wherever Christians are found happiness is found too. Not the shallow delight of a Pacific lagoon. Real happiness.
I Peter 3:12-15 The eyes of the Lord are over the righteous, and his ears are open unto their prayers: but the face of the Lord is against them that do evil. And who is he that will harm you, if ye be followers of that which is good? But and if ye suffer for righteousness' sake, happy are ye: and be not afraid of their terror, neither be troubled; but sanctify the Lord God in your hearts: and be ready always to give an answer to every man that asketh you a reason of the hope that is in you with meekness and fear
† I just checked. Two feet is maximum range.
