We show we truly love and know God if we obey Him. We obey Him, in part, by walking as Jesus walked, and Jesus gave us a new commandment to follow. But it wasn’t really a new commandment, just a new way of understanding. In John 12:34, Jesus said:
“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.”
It’s really a reiteration of an old commandment:
Mark 12:28-31 “And one of the scribes came up and heard them disputing with one another, and seeing that he answered them well, asked him, ‘Which commandment is the most important of all?’ Jesus answered, ‘The most important is, “Hear, O Israel: The Lord our God, the Lord is one. And you shall love the Lord your God with all your heart and with all your soul and with all your mind and with all your strength.” The second is this: “You shall love your neighbor as yourself.” There is no other commandment greater than these.’“
However, there is a new twist, and that twist is Jesus! Because of our relationship with Jesus, we can and should be able to love. No, it’s actually more than that. We must love. If we don’t love, we show that we are still in darkness. When we believe in Jesus we receive forgiveness, we enter into a relationship with God, and we experience victory over Satan! All that means we can now love our brothers and sisters in Christ! In contrast, we shouldn’t love the world or the things in the world. The things of this world don’t last.
Here is a great reminder: to know the Father you have to know the Son. If you deny the Son, you really are denying the Father. There are those in this world who want us to deny Jesus: they are called antichrists. Their presence is a sign we are in the last days. Some who are against Christ have actually been involved in the church, but they left and showed who they really served. Perseverance is a sign of true faith, and it’s the Spirit who keeps us in the straight and narrow and helps us to remain true. The Spirit is who reveals the true nature of the false teachers. That’s the context of “you have no need for anyone to teach you.” If we truly are believers, we obey, we love, and we persevere: we have the Spirit to thank for that!
