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 wrote to you, fathers, because you have come to know Him who is from the beginning. I wrote to you, young men, because you are strong, and the word of God abides in you, and you have overcome the evil one.
He that believes in the Son of God has the testimony in himself; he that does not believe God has made Him a liar, because he has not believed in the testimony which God has testified concerning His Son.
