"Peter said, “We’ve left our homes to follow you.” “Yes,” Jesus replied, “and I assure you that everyone who has given up house or wife or brothers or parents or children, for the sake of the Kingdom of God, will be repaid many times over in this life, and will have eternal life in the world to come.”" (Luke 18:28-30)
Peter and the other disciples had paid a high price for following Christ. They even paid the ultimate price after Christ's ascension! Here Christ reminded Peter (and us) that following Him has its benefits as well as its sacrifices. Are you worried about what you have to give up in order to say yes to Christ? All of us has to pay this price at a point in our Christian walk, but take courage in the promise of the Master that their is always a short term and long term reward for every sacrifice you make. Trust the Master to deliver on His word. He's NEVER failed to do that!
