'Everything' in the Bible

For everything that is in the world the desire for fleshly gratification, the desire for possessions, and worldly arrogance is not from the Father but is from the world.

The anointing you received from God abides in you, and you do not need anyone to teach you this. Instead, because God's anointing teaches you about everything and is true and not a lie, abide in him, as he taught you to do.

If our hearts condemn us, God is greater than our hearts and knows everything.
