1 John 5:3:
For this is the love of God, that we keep His commandments.
And His commandments are not burdensome.
Do you not know that friendship with the world is enmity with God?
Whoever therefore wants to be a friend of the world makes himself an enemy of God.
1 John 2:15-17:
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.
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.
And the world is passing away, and the lust of it;
but he who does the will of God abides forever.
For do I now persuade men, or God? Or do I seek to please men?
For if I still pleased men, I would not be a bondservant of Christ.
A man that has friends must show himself friendly:
and there is a friend that sticks closer than a brother.
