As John writes that we should keep God’s commandments and keep from sinning he once again brings clarity into the dilemma presented us. What dilemma? How is it possible for us who are sinful to live without sin or even not wanting to sin? The secret is this. His commandment, better translated His instruction is, “That we believe in the name of His Son Jesus Christ and love one another.
We put our trust, our hope in Jesus Christ. As John writes, if we do this, abide in Jesus He abides in us. We will know this by the Spirit abiding in us and through the Spirit we love one another and live life abundantly. 

Question: What was the Apostle John like?

Answer: John was especially loyal to Jesus. He was the only one of the 12 apostles present at the cross. After Pentecost, John teamed up with Peter to fearlessly preach the gospel in Jerusalem and suffered beatings and imprisonment for it. John underwent a remarkable transformation as a disciple, from the quick-tempered Son of Thunder to the compassionate apostle of love.  John experienced the unconditional love of Jesus firsthand, and he preached that love in his gospel and letters.
