If we say, "We have not sinned," we make Him a liar, and His word is not in us.
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 has not believed in the testimony that God testified concerning His Son.
Let the word of Christ dwell in you richly in all wisdom; teaching and admonishing one another with psalms, hymns, spiritual songs, singing with grace in your hearts, to God.
He who says, "I have known Him," and does not keep His commandments, is a liar, and the truth is not in him;
I wrote to you, fathers, because ye have known Him Who is from the beginning. I wrote to you, young men, because ye are strong, and the word of God abides in you, and ye have conquered the evil one.
