Since the love of God to us is real and genuine, we must genuinely love others too. Loving others with pretension is wrong. Hate what is wrong. Cling to what is good by having real love for others.
By doing this, we are also spreading the genuine love of God to others. This is God wants: people will love Him and will come to Him and experience His greatness. Experiencing God is the best feeling that you will ever had.
