John 14

John 14:21 "He who has My commandments and keeps them is the one who loves Me; and he who loves Me will be loved by My Father, and I will love him and will disclose Myself to him."
How do you know that you really love Jesus? You will know that you love Jesus if you obey Him and keep His words. The obedience is the proof that you really love Him.
You won’t be able to obey perfectly, but Jesus will know if your heart intent is to love Him. If you love Him, God the Father will love you, and Jesus will reveal Himself to you personally.
