'Things' in the Bible

Thus we are writing these things so that our joy may be complete.

(My little children, I am writing these things to you so that you may not sin.) But if anyone does sin, we have an advocate with the Father, Jesus Christ the righteous One,

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,

These things I have written to you about those who are trying to deceive you.

Now as for you, the anointing that you received from him resides in you, and you have no need for anyone to teach you. But as his anointing teaches you about all things, it is true and is not a lie. Just as it has taught you, you reside in him.

that if our conscience condemns us, that God is greater than our conscience and knows all things.

and whatever we ask we receive from him, because we keep his commandments and do the things that are pleasing to him.

I have written these things to you who believe in the name of the Son of God so that you may know that you have eternal life.
