Jesus, True God and Eternal Life
We know that we are from God, and the whole world lies in the power of the evil one. And we know that the Son of God has come and has given us understanding, so that we may know him who is true; and we are in him who is true, in his Son Jesus Christ. He is the true God and eternal life. Little children, keep yourselves from idols.
1 John 5:19–21
The Apostle John’s first letter to the saints clarifies the difference between those who belong to God and those who belong to this world so that the they may have fellowship and joy in Christ.
