Beloved, if God so loved us, we also ought to love one another. No one has seen God at any time. If we love one another, God abides in us, and His love has been perfected in us.
We are called to love one another. For when we love one another the Lord is manifested in our lives. The love of God cannot be counterfeited. It is only possible because the work and power of the Holy Spirit at work in our lives. If we claim to follow Christ then it is natural that we are filled with His love and His grace.
It is impossible to claim to follow Jesus Christ and not reflect His character and His love. I mean someone can simply give God lip service, but it is not until we have given the Lord our whole heart that we are born again. To follow Jesus Christ means a willingness on our part to lay down our lives. Jesus said that they would know His disciples by His love. As we grow in Christ His love naturally fills every area of our lives.
