John shares a three-fold explanation for his efforts in writing a letter to the churches.

John opens himself up for cross-examination from his skeptics, allowing them a chance to speculate on just who this Jesus of Nazareth really is.

The motive behind the instructions to abide in Jesus encompasses the forgiveness of our sins, abiding in God's love, sharing that love with our neighbors, and claiming victory in the ultimate spiritual war for souls.

Those who abide in God will find that there is no room for envy, hatred, or jealousy - anything outside of love has no place in the hearts of Believers.

Continuing on in his description of the extent of God's love, John continues to provide assurance of salvation to his readers.

God's love for us is demonstrated through Jesus' sacrifice; His love in us being lived out brings further glory to Him.

In the middle of reminding his readers to agape love one another, John provides them with a test to see if a teacher is in Christ or not.

After inviting his readers to continue to pray to God, John openly reminds them of what God's primary will is: that they believe in His Son, and that they love one another.

John echoes James' letter to the Churches by showing that since God demonstrates His love to us through Jesus, how can we withhold love for one another?

Using the example of Cain and Able, John follows up his instruction on how the people of God ought to love one another.
