This rich young ruler did not get it. If we would have sold everything he had, and gave to the poor, he would have become much richer than he was before.Actually, Jesus commended the rich young man for the good he did and told him he lacked one thing yet. He was not willing to give up that one thing to follow Jesus. That is why Jesus said it is difficult for a rich man to enter the kingdom of heaven.
This world says sell and keep your profits for yourself, God say sell and give away, and you will get much more in return!!
Jesus's disciples heard what he said to this young ruler, and wondered who can be saved then.
Luk 18:26 And they that heard it said, Who then can be saved?
Luk 18:27 And he said, The things which are impossible with men are possible with God.
Luk 18:28.. Then Peter said, Lo, we have left all, and followed thee.
Luk 18:29.. And he said unto them, Verily I say unto you, There is no man that hath left house, or parents, or brethren, or wife, or children, for the kingdom of God's sake,
Luk 18:30.. Who shall not receive manifold more in this present time, and in the world to come life everlasting.
If we really love the Lord with all our heart, mind, soul, and strength we will do exactly what he says.
