'Know' in the Bible

Then, with the eyes of your hearts enlightened, you will know the confidence that is produced by God having called you, the rich glory that is his inheritance among the saints,

that is, you will know the love of the Messiah which transcends knowledge, and will be filled with all the fullness of God.

However, that is not the way you came to know the Messiah.

For you know very well that no immoral or impure person, or anyone who is greedy (that is, an idolater), has an inheritance in the kingdom of the Messiah and of God.

because you know that everyone will receive a reward from the Lord for whatever good he has done, whether he is a slave or free.

Masters, treat your slaves the same way. Do not threaten them, for you know that both of you have the same Master in heaven, and there is no favoritism with him.

So that you may know what has happened to me and how I am doing, Tychicus, our dear brother and a faithful minister in service to the Lord, will tell you everything.

I am sending him to you for this very reason, so that you may know how we are doing and that he may encourage your hearts.
