In the book of 1 John, there are laid out 3 tests by which we can examine ourselves to see that we are in the faith. By doing so and passing the test we can have assurance of eternal life – 1 John 5:13.
The Second test is the Social Test – Do you Love your Neighbour?
The Commandment to Love one another was 1. To be so from the beginning, 2. Confirmed and renewed in Christ and 3. Is to be seen in the life of God’s people.
John says it like this – “Whoever says he is in the light and hates his brother is still in darkness. Whoever loves his brother abides in the light, and in him there is no cause for stumbling.” – 1 John 2:4
Jesus says, “By this all people will know that you are my disciples, if you have love for one another” John 13:35
This old command to love one another is confirmed and renewed in Christ who tells us that love for one another is not optional if we are to be his disciples and requires that we love all people, even our enemies and that we are to love as he also loved, “A new commandment I give to you, that you love one another: just as I have loved you, you also are to love one another.” John 13:34
