Let the word of Christ dwell in you richly, teach and admonish one another in all wisdom, and sing psalms and hymns and spiritual songs with thankfulness in your hearts to God.
I write to you, fathers, because you know him who is from the beginning. I write 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 in the Son of God has the testimony in himself. He who does not believe God has made him a liar, because he has not believed in the testimony that God has borne to his Son.
