What does the Bible say about not loving the world?

In 1 John 2:15-17, the Apostle John clearly states that believers are commanded not to love the world or the things in it. This love for the world signifies an alignment with its evil system, which is fundamentally opposed to God. The passage asserts that if anyone loves the world, the love of the Father is not in him, indicating that these two affections cannot coexist. True believers are called to align their hearts with God and pursue holiness, rejecting worldly values and desires that compromise their relationship with Him.
