Mark 10:17-27
New American Standard Bible
The Rich Young Ruler
17 As He was setting out on a journey, a man ran up to Him and knelt before Him, and asked Him, “Good Teacher, what shall I do so that I may inherit eternal life?” 18 But Jesus said to him, “Why do you call Me good? No one is good except God alone. 19 You know the commandments: ‘Do not murder, Do not commit adultery, Do not steal, Do not give false testimony, Do not defraud, Honor your father and mother.’” 20 And he said to Him, “Teacher, I have kept all these things from my youth.” 21 Looking at him, Jesus showed love to him and said to him, “One thing you lack: go and sell all you possess and give to the poor, and you will have treasure in heaven; and come, follow Me.” 22 But he [a]was deeply dismayed by [b]these words, and he went away grieving; for he was one who owned much property.

23 And Jesus, looking around, *said to His disciples, “How hard it will be for those who are wealthy to enter the kingdom of God!” 24 And the disciples were amazed at His words. But Jesus responded again and *said to them, “Children, how hard it is to enter the kingdom of God! 25 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.” 26 And they were even more astonished, and said to Him, “[c]Then who can be saved?” 27 Looking at them, Jesus *said, “With people it is impossible, but not with God; for all things are possible with God.”
