ἀληθῶς

But if anyone keeps His word, the love of God has been truly perfected in him. By this we know that we are in Him:

When Jesus saw Nathanael approaching, He said of him, “Here is a true Israelite, in whom there is no deceit.”

When the people saw the sign that Jesus had performed, they began to say, “Truly this is the Prophet who is to come into the world.”

So He said to the Jews who had believed Him, “If you continue in My word, you are truly My disciples.

But I tell you truthfully, some who are standing here will not taste death before they see the kingdom of God.”
