In the warnings of possible costs in Luke 9:57-62; 14:25-30, He says we must expect the loss of the respect and association with those we feel the most affection for, family members. They are not going to appreciate the changes we have made in our lives. They are yet blinded because God has not removed the veil covering their spiritual perceptions. This happens to many of us. It occurred in my relationship with my parents.
Jesus warns that our lives may become seriously unstable, as outsiders might judge it. He suggests that the convert may become somewhat itinerant, seeming to have an unsettled existence. He also suggests that following Him would put demands on our lives and time that might cut close family members to the quick, perhaps even turning them into enemies. Christ makes plain that, despite God's well-known mercy, He wants our wholehearted, unreserved loyalty with no yearning ever to turn back to our former lives. It is in meeting challenges like these that the potential costs become realities.
Though not mentioned directly here, Hebrews 11 reminds us of those who were tortured by mocking and scourging, by imprisonment, by stoning, and even by being sawn in two. Others were forced to flee for their lives, wandering destitute and tormented, barely able to clothe themselves. This may not happen to many of us now, but as matters intensify, Jesus warns that people will eventually kill Christians, thinking that they are glorifying God.
