Peter began to say to him, "We have given up everything and followed you." Jesus said, "Amen, I say to you, there is no one who has given up house or brothers or sisters or mother or father or children or lands for my sake and for the sake of the gospel who will not receive a hundred times more now in this present age: houses and brothers and sisters and mothers and children and lands, with persecutions, and eternal life in the age to come. But many that are first will be last, and (the) last will be first." (Mk 10:28-31)
Jesus had many followers. There were those who followed him but still holding on to their wealth, relatives and other things. There were still others who left certain things but holding on to certain other things and followed him. But there were few who left everything to follow Jesus.
Reward and honour are given to only those who give up properties, relations and possessions for the sake of Jesus and his Gospel. Interestingly what is given up is given back a hundredfold. It only goes to say that there is no real giving up on this earth. Man will always possess material thing and will have human relations.
Extra rewards are the ones that have to be considered. They are persecutions and eternal life. Persecutions on this earth and eternal life in the next. To be a follower of Jesus on this earth necessarily mean persecutions on this earth. The world is after material wealth and human relations and naturally giving up of these are contrary to the world. Every time when one rejects these and rewarded back a hundredfold then there is suffering for the one who gives up. But persecution is for following Jesus and his gospel. The real reward and the only reward is eternal life that is a gift that is given by God.
