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 write to you, fathers, because you have known Him who is from the beginning. I have written to you, young men, because you are strong, and the Word of God abides in you, and you have overcome the evil one.
He who believes on the Son of God has the witness in himself. He who does not believe God has made Him a liar, because he does not believe the record that God gave of His Son.
