Why does one man think he has the right to force his ideology down the worlds throat, and why is half the population helping him?
Because they are part of the world.
1 John 2:15-17
Do not love the world, nor the things in the world. If anyone loves the world, the love of the Father is not in him.
For all that is in the world, the lust of the flesh and the lust of the eyes and the boastful pride of life, is not from the Father, but is from the world.
And the world is passing away, and also its lusts; but the one who does the will of God abides forever.
John 16:33
These things I have spoken to you, that in Me you may have peace. In the world you have tribulation, but take courage; I have overcome the world.
The Lord Jesus Christ’s words to His disciples about the world: read John 14-16
John 3:16 = His victory
