God required all his people to make adjustments: Abraham, Moses, etc. He expects us to make adjustments too.
The Gospel never changes but it changes us . God calls on us, if we are to follow Him, to take up our cross and change.
The Rich Young Ruler approached Jesus and asked, "What else must I do? What adjustments should I make?" He had come a long way and was much closer to truth than many. But he lacked one thing he needed to adjust. Jesus told him to sell all he had and give to the poor. He refused to make the change that he Son of God requested. The man was unwilling to let God sit on the throne of his heart. He held onto the god of money.
