When we think that we can manage without Jesus - we do!  Whatever contributes to that state of arrogance is an idol, a false god, a spiritual obstacle to relating to the true God.  Wealth, in its many forms, gives a false sense of security which appears to make faith in God redundant.  When Jesus said it was 'easier for a camel to go through the eye of a needle than for someone who is rich to enter the kingdom of God', some commentators suggest that Jesus’ metaphor was of a camel kneeling down and shuffling through a narrow archway.  But the word used is clear – how can a camel go through the eye of a sewing needle?  Totally impossible!
 
The disciples had just been shocked to see how a rich young man would not give his money away to follow Jesus; preferring the apparent security and social position his wealth offered (Matthew 19:16-22).  After all, many apparently religious people were also quite rich (Matthew 23:5-7).  If those people could not be saved, then what hope was there for others in Israel?  They had grown up with the idea that the more holy a person was, the wealthier they would become. They might have taken Abraham, Jacob, David and Solomon as their examples.  Indeed, increased crops, livestock, children and land were part of the blessings which flowed from obeying the Old Covenant (Deuteronomy 28:1-6).
 
But Jesus was bringing a New Covenant to make human beings acceptable to God, with eternal rewards which might never be seen in this life (2 Timothy 4:8).  Those blessings could never come by obeying the law: they are only granted to people who admit their sinfulness and cry out for mercy, trusting in Christ’s own sacrifice for their sin (1 Peter 2:24).  Wealth, of any amount or none, is irrelevant (Luke 21:1-4).  When faith in Christ replaces the self-sufficiency of wealth – the impossible becomes a miracle.  Only God can change hearts to love and trust Him, if that is what they really desire.  
 
There are some believers who have a lot of money and property: but not many (1 Corinthians 1:26-31).  When the wealthy are converted it is because God defeats 'the deceitfulness of wealth' (Matthew 13:22) which always tries to choke God's Word.  But make no mistake - the world, flesh and devil will use anything which pretends to offer security to turn people away from the truth of God's Word and the need to submit to Him ... even with those who have started to put their trust in Him.  If that is your problem, do away with that false security - as Jesus instructed the rich young man (Matthew 19:16-22).
