We must OVERCOME this world by loving God and His ways as revealed by and in Jesus and NOT love the world.
15 Do not love the world or the things in the world. If anyone loves the world, the love of the Father is not in him.
16 For all that is in the world—the lust of the flesh, the lust of the eyes, and the pride of life—is not of the Father but is of the world.
17 And the world is passing away, and the lust of it; but he who does the will of God abides forever.
1 John 2:15-17
33 “These things I have spoken to you, that in Me you may have peace. In the world you will have tribulation; but be of good cheer, I have OVERCOME the world.”
John 16:33
The rewards Jesus offers are directly related to overcoming. In each church’s case it is something different but still consistent with Jesus teaching

Revelation 3:12

20 “Behold, I stand at the door and knock. If anyone hears My voice and opens the door, I will come in to him and dine with him, and he with Me.
