1 John 5:19-21 Holman Christian Standard Bible (HCSB)
19 We know that we are of God, and the whole world is under the sway of the evil one.
20 And we know that the Son of God has come and has given us understanding so that we may know the true One.[a] We are in the true One—that is, in His Son Jesus Christ. He is the true God and eternal life.
21 Little children, guard yourselves from idols.
