A God of Love would not have created such a world full of disharmony.
What we fail to take into account is that what we love most in the world usually runs counter to God’s Pure Love.
For one thing, it is not in this world that we should find our happiness, putting all our attention on self-centered concerns. This belief causes us to blame everything bad that happens to us on outer circumstances. But Jesus told Pontius Pilate (who represented the worldly human reasoning mind) that His kingdom was within.
Few people these days understand this unique premise.
What it means is that heaven (or hell) is not some place you go to, but is something you become. God puts misfortune and failure before us so that we will see that the physical world can never offer us true happiness—in order that we might change our focus (and wake up) to working on improving the more interior qualities of our hearts and minds.
Certainly, the length of our lifespan on earth, which is relatively short, cannot possibly make living a corporeal life worth all our effort and energy.
Scientist/theologian Emmanuel Swedenborg discovered that we earth-humans would actually see God as our enemy if we could see what the Creator had planned for us through Divine Providence. Only when we begin to sense our true cosmic responsibility do we begin to treat our misfortunes differently—as blessings, designed to get us back on the right spiritual track.
