Everything in life has a cost and brings consequences. If you buy a car, additional costs are generated such as fuel purchase, washing, maintenance, etc. If you have a child, additional fixed expenses are also generated, such as diapers, clothing, food, etc. In short, the point is that in life everything has a cost and following Jesus is no the exception.
Many believe that serving Jesus is like going on vacation to a five-star hotel, or that Jesus is an Aladdin or Santa Claus who fulfills all wishes. Jesus is more than all of that and therefore, to follow Him is a higher cost than everything else.
In the whole history of the church, serving Jesus has always represented a high cost, and we have seen this since the death of Stephen in Acts 7 to this day, because, in countries like Nigeria, Egypt, China, Afghanistan, among others, it is still difficult to preach the gospel. And of course, if we read the book of the Martyrs written by John Fox, we will realize how much it costed the reformers to preach the gospel of Jesus Christ.
