Ephesians 4: 17 to 24: What are these verses about?

What we are saying here is that when we hear the word of God, that is, the words of Jesus in the four gospels, Jesus' words are also life, and we must act, because these words have the ability to renew us and use the word of God, that is, the truth, to overcome the old habits of the old people in us, and we are new people. If you learn from Christ and don't indulge yourself, you will be a cripple with mental death.
