"So I say, walk by the Spirit, and you will not gratify the desires of the flesh. For the flesh desires what is contrary to the Spirit, and the Spirit what is contrary to the flesh."
We know what real love is because Jesus gave up his life for us. So we also ought to give up our lives for our brothers and sisters.
What do you love? When we put our value in things, relationships, money, etc. we lose sense of our purpose. The kingdom of God is forever and our value our worth, our love is all because of God.
