The context of Lukes passage is, take a guess; believers, not unbelievers, so, it only applies to the born-again, and thus it excludes your proof-texting methodology.
Therefore you are the one in error, failing yet again to intepret within context and misapplying a proof-text.
Excellent point Luke.
The story is also told here:
Then Jesus beholding him loved him, and said unto him, One thing thou lackest: go thy way, sell whatsoever thou hast, and give to the poor, and thou shalt have treasure in heaven: and come, take up the cross, and follow me. (Mark 10:21)
And he was sad at that saying, and went away grieved: for he had great possessions. (Mark 10:22)
--He was not saved. Instead of choosing Christ he chose his riches. Jesus demonstrated that the Ten Commandments which he said he kept from his youth up, he did not keep. He "coveted" his riches more than he desired Christ. That covetousness kept him from Christ.
Therefore Christ said;
And Jesus looked round about, and saith unto his disciples, How hardly shall they that have riches enter into the kingdom of God! (Mark 10:23)
--The believers Christ was talking to was his own disciples teaching them about rich people and their response to the gospel.
What was the disciples response?
And the disciples were astonished at his words. But Jesus answereth again, and saith unto them, Children, how hard is it for them that trust in riches to enter into the kingdom of God! (Mark 10:24)
