John’s first epistle focused on the characteristics of God that are expected to be seen in his children. John started out by saying that God is light and in him there is no darkness (1 John 1:5) and then stated, “If we say we have fellowship with him, and walk in darkness, we lie, and do not the truth” (John 1:6). John was pointing out that there should be similarities between Jesus’ behavior and our own. The way that we become like Jesus is by following his instructions and confessing our sins to God. John said, “If we live in the light as He is in the light, we share what we have in God with each other. And the blood of Jesus Christ, His Son, makes our lives clean from all sin.” (1 John 1:7, NLV).
John’s understanding of the transformation that occurs through spiritual rebirth was limited, but he saw Jesus as the pattern that all born-again believers were to follow. John acknowledged his limited understanding when he said, “Dear friends, we are God’s children now. But it has not yet been shown to us what we are going to be. We know that when He comes again, we will be like Him because we will see Him as He is” (1 John 3:2, NLV). John seemed to be saying that our eternal existence begins the moment we accept Jesus as our savior, but our likeness or similarity to Jesus is limited by our current physical form. John talked about seeing Jesus as if it was a requirement for the full manifestation of our eternal character to become operational.
John mentioned the quality of love numerous times in his first epistle. The Greek words agapao (ag-ap-ah’-o) and agape (ag-ah’-pay) appear more than 20 times in the second and third chapters of 1 John alone. John said, “Hereby perceive we the love of God, because he laid down his life for us: and we ought to lay down our lives for the brethren” (1 John 3:16). John went on to say that our love for other believers should be demonstrated in tangible ways that can be measured (1 John 3:18) and then, he said about God, “And whatsoever we ask, we receive of him, because we keep his commandments, and do those things that are pleasing in his sight” (1 John 3:22).
John implied there was a connection between obedience to God’s commandments and getting answers to our prayers. John clarified what he meant by keeping God’s commandments when he stated, “And this is his commandment, That we should believe on the name of his Son Jesus Christ, and love one another, as he gave us commandment” (1 John 3:23). Basically, what John was saying was that all God requires us to do in order to be blessed by him is to be born again and to love each other, but according to John, our ability to love others isn’t even dependent on us; it’s dependent on the indwelling of the Holy Spirit (1 John 3:24).
Jesus connected being born again with the indwelling of the Holy Spirit and made it seem as if these two aspects of spiritual life were essentially one and the same. Jesus told Nicodemus:
Whatever is born of the flesh is flesh. Whatever is born of the Spirit is spirit. “Do not be surprised that I said to you, ‘You must be born again.’ The wind blows where it wants to and you hear its sound. You do not know where it comes from or where it goes. It is the same with everyone who is born of the Spirit of God.” (John 3:6-8, NLV)
Jesus indicated that the only requirement for being born again was to believe in him. He said, “For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life” (John 3:16).
John identified God as the source of agape or unselfish love and went so far as to say that apart from God it is impossible for us to love each other the way God loves us. He stated, “Dear friends, let us love each other, because love comes from God. Those who love are God’s children and they know God. Those who do not love do not know God because God is love.” (1 John 4:7-8, NLV). John indicated that God demonstrated his unselfish love toward us by sending his son Jesus into the world to be the propitiation for our sins (1 John 4:9-10) and then he stated, “Beloved, if God so loved us, we ought also to love one another” (1 John 4:11).
