Although the disciples were shocked at the difficulties a rich person would encounter when trying to enter Christ’s kingdom, they were reassured that nothing was impossible for God. Jesus then went on to validate their extreme sacrifice of leaving all to follow Him. In the end, nothing was lost. In fact, not only would they inherit eternal life now (knowing God and Jesus Christ whom he sent- see John 17:3) but after the ressurection they would receive one hundred fold of all they gave up. -Teresa
Matthew 19: 23-30 (ESV)
23 And Jesus said to his disciples, “Truly, I say to you, only with difficulty will a rich person enter the kingdom of heaven. 24 Again I tell you, it is easier for a camel to go through the eye of a needle than for a rich person to enter the kingdom of God.” 25 When the disciples heard this, they were greatly astonished, saying, “Who then can be saved?” 26 But Jesus looked at them and said, “With man this is impossible, but with God all things are possible.” 27 Then Peter said in reply, “See, we have left everything and followed you. What then will we have?” 28 Jesus said to them, “Truly, I say to you, in the new world,[a] when the Son of Man will sit on his glorious throne, you who have followed me will also sit on twelve thrones, judging the twelve tribes of Israel. 29 And everyone who has left houses or brothers or sisters or father or mother or children or lands, for my name’s sake, will receive a hundredfold[b] and will inherit eternal life. 30 But many who are first will be last, and the last first.
