"A Story is told about William Randolph Hearst, the late newspaper publisher. Hearst invested a fortune in collecting great works of art. One day he read about some valuable pieces of art and decided that he must add them to his collection. He sent his agent abroad to locate and purchase them. Months went by before the agent returned and reported to Hearst that the items had at last been found – they were stored in his own warehouse. Hearst had purchased them years before!
"That is analogous to the alarming number of Christians today who are on a desperate search for spiritual resources they already possess. Theirs is a futile quest for something more. It’s a heretical fire fanned in part by the false notion that salvation is insufficient to transform believers and equip them for Christian living. Those thus influenced believe they need something more – more of Christ, more of the Holy Spirit . . .But as we have been seeing, to have Jesus is to have every spiritual resource. All we need is found in Him. Rather than attempting to add something to Christ we must simply learn to use the resources that are already ours in Him."
