My dearly-loved friends, it is no new command that I am now giving you, but an old command which you have had from the very beginning. By the old command I mean the teaching which you have already received.
But we, even while we speak in this tone, have a happier conviction concerning you, my dearly-loved friends–a conviction of things which point towards salvation.
As for you, let the teaching which you have received from the very beginning continue in your hearts. If that teaching does continue in your hearts, you also will continue to be in union with the Son and with the Father.
Dear friends, we are now God's children, but what we are to be in the future has not yet been fully revealed. We know that if Christ reappears we shall be like Him, because we shall see Him as He is.
Dear friends, do not believe every spirit, but put the spirits to the test to see whether they are from God; for many false teachers have gone out into the world.
