'Things' in the Bible

And we are writing these things to you so that our joy may be made complete.

My little children, I am writing these things to you so that you may be without sin. And if any man is a sinner, we have a friend and helper with the Father, Jesus Christ, the upright one:

Have no love for the world or for the things which are in the world. If any man has love for the world, the love of the Father is not in him.

But as for you, keep in your hearts the things which were made clear to you from the first. If you keep these things in your hearts you will be kept in the Father and the Son.

I am writing these things to you about those whose purpose is that you may be turned out of the true way.

As for you, the Spirit which he gave you is still in you, and you have no need of any teacher; but as his Spirit gives you teaching about all things, and is true and not false, so keep your hearts in him, through the teaching which he has given you.

When our heart says that we have done wrong; because God is greater than our heart, and has knowledge of all things.

And he gives us all our requests, because we keep his laws and do the things which are pleasing in his eyes.

I have put these things in writing for you who have faith in the name of the Son of God, so that you may be certain that you have eternal life.
