Are you pursuing the temporal things of this world or the eternal treasure that only Jesus offers?
From what I understand, Johnny Cash turned his back on God in pursuit of the things of this world. He gained it all: fame, money, success, etc. , but he forfeited his own soul in the process. It wasn't until later in life that Johnny Cash returned to the Lord. I'm sure that he probably had many regrets for the path that he chose in life. All the things that he formerly counted as gain, he later counted as loss in comparison to the riches found in Christ Jesus. This video shows that.
"For what shall it profit a man, if he shall gain the whole world, and lose his own soul?" Mark 8:36
