I explained this.
The person who considers himself rich is prideful and trusting in his own capacity to save himself and solve his own problems.
Ephesians 2 tells us that ALL of us were dead in our trespasses and sins.
However, we quickly read, "But God."
Tell me, what is it that God did, even while we were still dead?
Here is the passage so you can tell us.
Ephesians 2:1-9 And you were dead in the trespasses and sins in which you once walked, following the course of this world, following the prince of the power of the air, the spirit that is now at work in the sons of disobedience— among whom we all once lived in the passions of our flesh, carrying out the desires of the body and the mind, and were by nature children of wrath, like the rest of mankind. But God, being rich in mercy, because of the great love with which he loved us, even when we were dead in our trespasses, made us alive together with Christ—by grace you have been saved— and raised us up with him and seated us with him in the heavenly places in Christ Jesus, so that in the coming ages he might show the immeasurable riches of his grace in kindness toward us in Christ Jesus. For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, not a result of works, so that no one may boast.
Now notice that you said it was harder for a rich man to enter the kingdom, but Matthew 19:23-24 doesn't say that. It says...
And Jesus said to his disciples, “Truly, I say to you, only with difficulty will a rich person enter the kingdom of heaven. 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.”
Luke 18:24-26 says: Jesus, seeing that he had become sad, said, “How difficult it is for those who have wealth to enter the kingdom of God! For 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.” Those who heard it said, “Then who can be saved?”
Where is the word "harder?"
Note that the hearers had a "prosperity gospel" mentality and thought the mans wealth meant he was more blessed than the poor. Jesus informed them that self reliant people have a hard time being reliant wholly upon God alone.
There are many in the church today who would walk away if Jesus asked them to give all their wealth away. They go to church as a status symbol in the community. Are they saved? Only God knows.
