Let the word of Christ dwell in you richly in all wisdom; teaching and admonishing one another in psalms and hymns and spiritual songs, singing with grace in your hearts to the Lord.
I have written unto you, fathers, because you have known him who is from the beginning. I have written unto you, young men, because you are strong, and the word of God abides in you, and you have overcome the wicked one.
He that believes on the Son of God has the witness in himself: he that believes not God has made him a liar; because he believes not the witness that God gave of his Son.
