As for you, what you have heard from the beginning must remain in you. If what you heard from the beginning remains in you, you also will remain in the Son and in the Father.
And as you Philippians know, at the beginning of my gospel ministry, when I left Macedonia, no church shared with me in this matter of giving and receiving except you alone.
Let the word of Christ dwell in you richly, teaching and exhorting one another with all wisdom, singing psalms, hymns, and spiritual songs, all with grace in your hearts to God.
What we have seen and heard we announce to you too, so that you may have fellowship with us (and indeed our fellowship is with the Father and with his Son Jesus Christ).
But if we walk in the light as he himself is in the light, we have fellowship with one another and the blood of Jesus his Son cleanses us from all sin.
Dear friends, I am not writing a new commandment to you, but an old commandment which you have had from the beginning. The old commandment is the word that you have already heard.
And we have come to know and to believe the love that God has in us. God is love, and the one who resides in love resides in God, and God resides in him.
Everyone who goes on ahead and does not remain in the teaching of Christ does not have God. The one who remains in this teaching has both the Father and the Son.
Therefore, remember what you received and heard, and obey it, and repent. If you do not wake up, I will come like a thief, and you will never know at what hour I will come against you.
