God makes it simple for people who only understand simple. For people willing and able to dig in deeper that is there as well... but sometimes that can be a dangerous thing for a person already tending to be proud of his abilities and accomplishments. This is include in what Jesus said here:
"Then said Jesus unto his disciples, Verily I say unto you, That a rich man shall hardly enter into the kingdom of heaven.
And again I say unto you, It is easier for a camel to go through the eye of a needle, than for a rich man to enter into the kingdom of God." Matt 19:23-24
Jesus is not talking only about money [as in "green back dollar bill" or "coin of the realm"] but that is also included. People with high I.Q.s, or an extensive educations, or born in a materially rich countries or countries with greater political and religious freedoms, or to a richer than the average family, or a person with very good physical health... and so forth... are all include in the words of Jesus. They have all of that stuff in their way standing effectively between them and God. They can still make it but the pathway is a more difficult one. Jesus clarifies what is to required of them versus what may be required of a poor man [in the same sense poor] here:
"But he that knew not, and did commit things worthy of stripes, shall be beaten with few stripes. For unto whomsoever much is given, of him shall be much required: and to whom men have committed much, of him they will ask the more." Luke 12:48
Much is given... much is required! Americans are from my own experience frequently guilty of missing this point. More Americans are rich in the things I mentioned and others than probably in most or even all of the countries on planet Earth today. Are they doing more as individuals? Consider what Jesus says here:
The truly amazing thing is , i used to be very world wise and intellecutal . A big wordly thinker
full of pride with all this knowledge i had attained . When GOD drew me to Christ
That mindset changed . He made me dumb to the world that i would become wise unto Him .
Yep , i went from highly intellectual to being a mere child . OH but i tell us all , That is a gift from GOD .
Now let all praise the glorious Lord .
"And Jesus sat over against the treasury, and beheld how the people cast money into the treasury: and many that were rich cast in much.
And there came a certain poor widow, and she threw in two mites, which make a farthing.
And he called unto him his disciples, and saith unto them, Verily I say unto you, That this poor widow hath cast more in, than all they which have cast into the treasury:
For all they did cast in of their abundance; but she of her want did cast in all that she had, even all her living." Mark 12:41-44
