There is a section of Scripture where Jesus says if we want to follow him, we need to hate our families, and our lives. Given that Jesus urges us to love God, and love people, this seems a little out of place.
Now, no one thinks Jesus meant actual hatred. The context concerns counting costs. He gives the comparison to building something, but not realizing how much money it will require. Or if a country is considering going to war, it needs to know how big of an army is needed.
Giving one's allegiance to Father, Son, and Spirit, is the first priority. Choices will need to be made. God still wants us to love, and honor, our families. God still wants us to care for our personal needs.
Pretend for a minute that we come from a family that does not know Jesus. We are the only person in our family, who follows Jesus. If we love our family, we want them to know, and follow, Jesus. So, love demands that we attempt to communicate the gospel to our family. What if they get mad? What if they say, "Don't talk about this anymore! If you do, you're not in the family anymore!" This choice, (to share or not to share), if we needed to make it, would in no way be easy. But the choice is between following Jesus and following our family. We would need to choose Jesus.
May no one ever need to make this decision. May every follower of Jesus's family see Jesus in us, and be amazed, and want Jesus for themselves.
Then, Jesus continues with a short parable about salt. Salt is necessary for life, especially in the Middle East in Jesus' time. It not only gave flavor to food, it acted as a preservative, enabling food to be saved for a longer time.
Following Jesus becomes salt to our families, friends, cities, nations, and culture. Those hard decisions bring life to our circles of existence. We are actually loving people by making those hard decisions to follow Jesus. Our lives are better for following Jesus. Their lives would be better for following Jesus.
