John, the gospel writer known as the beloved apostle, writes three epistles to the Gentiles to assure them of eternal life based on his eyewitness account. John touches on light, truth, and love throughout his writing and affirms the truth of who Jesus is. John reveals that the key to the Christian life is abiding and fixing our hope on Jesus. If we are not abiding, we are trying to do that which can only be accomplished by God in our own strength.
